Overqualification as a Blunt Weapon on Productivity Improvement: Person-Job Fit Theory Integration

Despite the growing number of studies that underlie the influence between perceived overqualification (POQ) and counterproductive behaviour (PKP), there is still a gap in the lack of research involving the role of affective mechanisms on the effect of POQ on PKP. In this study, researchers focused on the mediating role of job boredom (KTP) in the pathway of influence of POQ on PKP. Using a sample of 106 employees and lecturers at Islamic universities in Indonesia and using the integration of the theory of person-job fit, the researchers found that KTP fully mediates the effect of POQ on PKP.


Introduction
Along with the development of the labour market, in recent decades, the quality of the workforce has been increasing. Improving the quality of the workforce is accompanied by an increase in a person's level of education, which is getting higher but not proportional to the availability of job opportunities. Job seekers need higher education to compete for jobs, even jobs that do not require a high level of education and ability. With the gap between the qualifications of a workforce and job qualifications, the term perceived overqualification (POQ) appears. The perception of overqualification is a type of phenomenon in the global labour market. Workers feel that they have qualifications (e.g., education, skills, and experience) higher than the job requirements (Erdogan, Bauer, Piero, & Truxillo, 2011).
High levels of unemployment and workers losing their jobs can force an individual to stay in a job below their working capacity (Liu, Luksyte, Zhou, Shi, & Wang, 2014). Another fact that emerged is that overqualification does not only occur in developed countries (Maynard & Parfyonova, 2013) but is also found in many developing countries (Shen & Kuhn, 2013). The phenomenon of overqualification in developed and developing countries arises due to the lack of compensation benefits for unemployment, for example, social security benefits. With this phenomenon, the discussion of overqualification has received attention from researchers, practitioners, and the mass media, making it enjoyable to study in different research contexts (Liu, Luksyte, Zhou, Shi, & Wang, 2014).
Most previous studies related to overqualification (POQ) perceptions have focused more on attitudes, health, and welfare (Liu & Wang, 2012). However, overqualification can affect negative work behaviour and counterproductive behaviour (PKP) (Luksyte, Spitzmueller, & Maynard, 2011). For example, workers who have overqualified perceptions of themselves tend to suffer more due to low psychological well-being and show lower organizational commitment, so that it can lead a worker to negative work behaviours, such as counterproductive behaviour (Kim, Park, Shon & Lim, 2019). ). However, perceived overqualification (POQ) can provide mixed outcomes for workers and employers (Harari, Manapragada, & Viswesvaran, 2017). However, the big question is whether POQ can directly affect PKP or are there other factors involved in its influence? Considering the various outputs of the POQ.
Researchers include the mediating role of job boredom (KTP) to explain in detail the mechanism of why POQ affects PKP (Kim, Park, Shon & Lim, 2019). The mediating effect of job boredom has received less attention for previous research. However, the theme of job boredom is essential to study because it can affect work behaviour (e.g., counterproductive behaviour). Moreover, overqualified workers often experience job boredom in various industries (Harju, Hakanen, & Schaufeli, 2014). Industry or organization is an environment that can cause strong emotions for each member of the organization. Each individual in the organization has specific emotions that can impact certain behaviours, including job boredom.
Feelings of boredom that arise excessively can trigger the urge to run away from certain situations. Furthermore, a worker tends to engage in counterproductive behaviour (PKP) (Kim, Park, Shon & Lim, 2019) in a mechanism to reduce boredom. Thus, it can say that job boredom can play a crucial role in understanding the influence of counterproductive behaviour. However, the mediating role to link overqualification (POQ) with counterproductive behaviour (PKP) has not been studied empirically (Kim, Park, Shon & Lim, 2019).
The researcher integrates the theory of person-job (P-J) fit (Kristof-Brown & Guay, 2011). P-J fit emphasizes the fit between a worker and the job he has. The P-J fit theory states that when a worker feels that their work is not suitable for them, they can then give negative experiences such as job boredom. Referring to the empirical literature of P-J fit theory, inadequate levels of P-J fit can be associated with low job satisfaction, greater desire to leave work, low overall performance, low extra-role behaviour (OCB), and also counterproductive behaviour (PKP) (Kim, Park, Shon & Lim, 2019). Workers who have the perception of being overqualified and not suitable for a particular job can trigger negative feelings such as boredom at work, which, in turn, can lead to counterproductive behaviour.
Based on the theory of P-J fit, the researcher aims to examine the effect of perceived overqualification (POQ) and counterproductive behaviour (PKP) and the mediating role of job boredom (KTP) on the effect of perceived overqualification (POQ) on counterproductive behaviour (PKP) (Kim, Park, Shon & Lim, 2019;Liu, Luksyte, Zhou, Shi, & Wang, 2014). As a contribution to science, the current study offers empirical evidence of KTP occurring on the job as a causal mechanism of the relationship between critical variables (e.g., perceived overqualification and counterproductive behaviour). Researchers also tested the mediation model on the direct effect of POQ on PKP through KTP. With the results of the current study, researchers hope to offer knowledge about the mechanism of the mediating role of KTP on the influence between POQ and PKP, given the lack of literature discussing and testing these various variables (Kim, Park, Shon & Lim, 2019).

Perception of Overqualification as the basis for the Mismatch between Workers and their Jobs
Consistent with previous research (Liu, Luksyte, Zhou, Shi, & Wang, 2014;Maynard & Parfyonova, 2013;Kim, Park, Shon & Lim, 2019), researchers argue that person-job (P-J) fit is the most It is good to photograph the phenomenon of overqualification is a perception which states that a worker has excess qualifications which illustrate the mismatch between a worker and the qualifications required for the job. Specifically, workers who have excess qualifications make it possible to meet and even exceed the qualifications needed in completing the main tasks assigned by the organization (Liu, Luksyte, Zhou, Shi, & Wang, 2014). This impact occurs when a worker has excess qualifications they cannot practise specific skills. Therefore, they need challenges from work to develop their abilities. Furthermore, workers who cannot practice their skills and find challenges in a job can cause negative feelings such as lack of job satisfaction and encourage an increase in counterproductive behaviour (Luksyte, Spitzmueller, & Maynard, 2011).
Previous literature reviews on the theory of P-J fit (Kristof-Brown & Guay, 2011) stated that a worker's incompatibility with his job usually leads to adverse outcomes and vice versa; fit is a critical factor between workers and organizations to improve performance, attitudes, and positive behaviours. Related to work. In line with the theory of P-J fit, the poor fit between workers and their jobs can trigger low job satisfaction, high desire to leave work, and performance in general (Kim, Park, Shon & Lim, 2019), and also have an impact on poor psychological conditions (Liu, Luksyte, Zhou, Shi, & Wang, 2014). Moreover, previous research has shown that an overqualified worker can trigger the desire to look for another job (Maynard & Parfyonova, 2013) and deviant behaviours such as job boredom and counterproductive behaviour (Luksyte, Spitzmueller, & Maynard, 2011).

Persepsi Overkualifikasi dan Perilaku Kontraproduktif
Working in a job that does not match the job qualifications is one of the most frustrating experiences for a person. A worker who has a perceived overqualification may increase the tendency to counterproductive behaviour, which aims to relieve feelings of wasted valuable resources (e.g., time, energy, and knowledge) (Luksyte, Spitzmueller, & Maynard, 2011). Specifically, based on the theory of P-J fit, a person can respond to unfavourable situations in his work environment that cause not only feelings of frustration, but more broadly include negative emotions such as anger, dissatisfaction, hatred, and boredom (Harari, Manapragada, & Viswesvaran, 2017), and the consequences for emotional reactions that stimulate PKP (Kim, Park, Shon & Lim, 2019).
Integrating the theory of person-job fit, the researcher argues that POQ can positively affect PKP. Previous literature states that there are two types of PKP, namely PKP that harms the organization (e.g., criticizing organizational policies) and PKP that can harm individuals within the organization (e.g., speaking ill of colleagues) (Holtz & Harold, 2013). The researcher understands that PKP caused by POQ can be aimed at one of the targets (e.g., organizations or individuals). The P-J fit model states that a person's mismatch with his job can provide a bad experience for workers. A mismatch of worker qualifications with job requirements can trigger negative emotions (Harari, Manapragada, & Viswesvaran, 2017). People who have excess qualifications (e.g., skills, abilities, knowledge, and experience) will feel angry with their organizations for not providing job challenges (Luksyte, Spitzmueller, & Maynard, 2011) and can further trigger PKP: Hypothesis 1: Perception of overqualification has a positive effect on counterproductive behaviour.

Perception of Overqualification and Job Boredom
Building on the P-J fit theory and previous research, researchers understand that POQ can be integrated into the P-J fit model (Kim, Park, Shon & Lim, 2019;Liu, Luksyte, Zhou, Shi, & Wang, 2014). P-J fit relates to the compatibility or suitability between workers and their jobs. POQ is a perceived mismatch of worker qualifications (e.g., skills, abilities, knowledge, and experience) and job demands. When a worker feels unsuitable for his job, it can trigger negative experiences, such as job boredom (Kim, Park, Shon & Lim, 2019). Work boredom can be interpreted as an unpleasant feeling and negative influence from the work environment and is characterized by low passion and dissatisfaction that comes from low stimulation in the work environment (Reijseger, Schaufeli, Peeters, Taris, van Beek, & Ouweneel, 2013).
Following the definition presented by Reijseger, Schaufeli, Peeters, Taris, van Beek, & Ouweneel (2013), KTP is a form of emotional reaction to a work environment that is less stimulating for a worker and subsequently causes a worker to feel that their abilities are underutilized. Well, or even they feel there is no match between the qualifications they have (e.g., skills, abilities, knowledge, and experience) with job requirements (Liu & Wang, 2012). To support the argument that there is a relationship between POQ and KTP, the researcher includes previous research from Watt and Hargis (2010), which used a sample of workers in the health sector. The results of the study stated that there was a positive relationship between POQ and KTP. In addition, KTP can also affect jobs with low workloads and jobs that do not utilize skills (Kim, Park, Shon & Lim, 2019).

Job Boredom and Counterproductive Behavior
The current research is built and integrated with the theory of P-J fit, which emphasizes more on the suitability and suitability of a worker with the work he is doing by focusing on the emergence of negative emotions (Luksyte, Spitzmueller, & Maynard, 2011) by showing job boredom as part of an individual's assessment, and subsequently engage in counterproductive behaviour (van Hooff & van Hooft, 2014). PKP itself is defined as voluntary behaviour that can harm other organizations and individuals (Holtz & Harold, 2013). According to the P-J fit theory, which focuses on the suitability and suitability of workers' qualifications and job requirements, negative emotions arising from KTP can trigger an increase in PKP. To support this statement, Bruursema, Kessler, and Spector (2011) found that KTP positively influences PKP.

Mediation Role of Job Boredom on the Effect of Perceived Overqualification on Counterproductive Work Behavior
Job boredom is a negative emotion that plays a crucial role in understanding the influence of POQ and PKP. As evidence, the researcher uses supporting data from Liu, Luksyte, Zhou, Shi, & Wang (2014), which found that overqualified workers tend to experience anger towards work environment situations and lead to PKP behaviour. Furthermore, another study from Deng, Guan, Wu, Erdoan, Bauer, & Yao (2018) states that when a worker experiences a perception of overqualification, they will feel less skilled interpersonally, feel less socially accepted, and these negative emotions can reduce work productivity. They. From the two previous research findings, the researcher hopes that POQ can be positively related to PKP through the mediating role of KTP.
KTP arises when an individual's skills are above average, and job challenges are below average, so situations like this can lead to perceptions of overqualification (Liu & Wang, 2012). In addition, when a worker feels bored with his job, they often feel that they lack the knowledge, skills, and abilities used in carrying out a job. In other words, an overqualified worker believes that their job does not provide the variety they want and thus can engage in PKP (Kim, Park, Shon & Lim, 2019).
Based on the P-J fit theory, the researcher argues that overqualified workers tend to do a cognitive analysis of their incompatibility with their work environment (Liu, Luksyte, Zhou, Shi, & Wang, 2014). In addition, overqualified workers tend to experience adverse emotional reactions because their organization cannot meet their needs and challenges. These affective reactions include anger and hatred for situations and conditions that are not favouring workers (Gibson & Callister, 2010). From the two types of affective reactions, it can say that there is poor compatibility between workers and their jobs. The research of van Hooff & van Hooft (2014) states that KTP can mediate the effect of POQ on PKP. Liu and Wang (2012) support the findings, which state that VAW can be an emotional reaction to POQ and directly encourage maladaptive work behaviour. Logically, the incompatibility felt by workers with their work can lead to a lack of stimulation at work, and then workers feel bored, so they tend to be involved in PKP. Research on POQ emphasizes that VAW plays a crucial role in explaining the mechanism of indirect influence of POQ on PKP ( The research refers to the positivistic paradigm that emphasizes the causality mechanism between research variables and uses a deductive quantitative research approach (Maksum, Handoko, & Fikriah, 2020). Collecting research data using cross-sectional by collecting data at a specific time using a questionnaire. The purpose of cross-sectional is to capture a picture of the phenomenon at a specific time and confirm the research hypothesis formulated in this study (Cooper & Schindler, 2014).
Researchers recruited 106 respondents who worked full time. In recruiting activities, the researcher aims to collect information from respondents who include respondents from various Islamic-based public and private universities and young people. Researchers set the criteria for workers working in Islamic-based public and private universities and young respondents because respondents with these criteria tend to experience perceptions of overqualification and are easier to engage in counterproductive behaviour (Luksyte, Spitzmueller, & Maynard, 2011). Research by Green & Zhu (2010) shows support for the opinion of the researcher that the perception of overqualification tends to occur among workers who are still relatively young, for this reason, the researchers recruited young workers who work at various state and private Islamic Universities in several areas within the scope of Indonesia. Researchers set an age limit for respondents between 25 to 45 years (Luksyte, Spitzmueller, & Maynard, 2011) who work in banking organizations and have at least one year of service.

Measurement
The researcher determined each measurement instrument used to measure the research variables using a five-point Likert scale starting with points 1 (strongly disagree) to 5 (strongly agree).
Perception of Overqualification -POQ. Researchers measure POQ using a 9-item measurement scale adopted from the Perceived Overqualification scale developed by Maynard, Joseph, & Maynard (2006), which has been validated and has been used in previous research (Kim, Park, Shon & Lim, 2019;Reijseger, Schaufeli, Peeters, Taris, van Beek, & Ouweneel, 2013;Harari, Manapragada, & Viswesvaran, 2017). Using a 5-point Likert scale (point 1, which means strongly disagree with pointing 5, which means strongly agree), respondents will assess the extent to which they consider themselves to have excess qualifications (ability, skills, knowledge, and experience) requirements. Used in their current job. The researcher includes several examples of question items used to measure POQ, namely "My job requires a lower education than my current education." In this study, Cronbach's Alpha achieved a score of 0.85 (Kim, Park, Shon & Lim, 2019). An example of another measurement item is "I have a higher ability than the required job requirements", with a Cronbach's Alpha score of 0.88 (Luksyte, Spitzmueller, & Maynard, 2011). A higher score indicates a higher perceived level of overqualification compared to a lower score.
Job Boredom -KTP. Researchers measure KTP using a 6-item measurement scale adopted from the Dutch Boredom scale developed by Reijseger, Schaufeli, Peeters, Taris, van Beek, & Ouweneel (2013), which is validated and has been used in previous studies (Kim, Park, Shon & Lim, 2019;Harju, Hakanen, & Schaufeli, 2014). The researcher used a 5-point Likert scale (point 1, which means strongly disagree with pointing five, which means strongly agree), respondents were asked to rate the extent to which they felt bored with their current job some time ago. The researcher also includes several examples of question items used to measure KTP, namely "I feel bored with my job", with a Cronbach's Alpha score reaching 0.85 (Kim, Park, Shon & Lim, 2019).
Counterproductive Behavior -PKP. Researchers measure PKP using a 19-item measurement scale adopted from the Workplace Deviance measurement scale developed by Bennett and Robinson's (2000), which is validated and used in previous research (Kim, Park, Shon & Lim, 2019). The study used a 5-point Likert scale (point 1, which means strongly disagree with pointing five, which means strongly agree), respondents were asked to rate the extent to which they have been involved in PKP during the last few moments. The researcher included a sample of question items such as "Saying something hurts someone at work" with a Cronbach's Alpha score of 0.93 (Kim, Park, Shon & Lim, 2019).

Procedure
Researchers collected research data in an online format using standard survey software. Respondents were recruited through various communication channels such as email and WhatsApp based on the provisions of the snowballing technique. Researchers start by contacting a network of colleagues, friends, and acquaintances, and then from that network can contact their colleagues, friends, and acquaintances to participate in the study. To avoid bias in the study results, the researcher included several screening questions to determine whether a respondent was eligible or not eligible to be used in the data testing process.
This study uses a validity test to ensure that the measurement scale used in the study is following the specified conceptual, operational and reliability definitions (Hair, Hult, Ringle, & Sarstedt, 2014). The validity tests used in this study are face validity and content validity (Maksum, Handoko, & Fikriah, 2020). Face validity aims to adapt the research instrument to the current research context by conducting discussions with experts . While in the content validity procedure, the researcher adjusts the overall content, definition, and research construct by reading and matching the existing literature (Hair, Hult, Ringle, & Sarstedt, 2014).
The researcher also added validity tests such as convergent validity and discriminant validity as the outer model test. Neuman (2016) states that convergent validity is a measuring tool that uses many indicators based on the logic that each indicator involved in a particular construct can have exciting movements and cluster in one place. Convergent constructs can be valid when the expected value of the factor load reaches a score of 0.4 to 0.7 and above (Hair, Hult, Ringle, & Sarstedt, 2014). Meanwhile, discriminant validity relates to the principle that different construct measures should not be highly correlated. The discriminant validity test was assessed based on the cross-loading measurement with each construct. The cross-loading value shows the correlation between each construct and its indicators and indicators from other block constructs. A construct has discriminant validity of the construct indicator has the highest loading value in its construct group (Hair, Hult, Ringle, & Sarstedt, 2014). The following evaluation compares the AVE root value for each construct with the correlation between the construct and other constructs in the model. The construct will be said to meet discriminant validity when the value of the square root of the AVE construct is greater than the value of the most significant correlation between the construct and other constructs. Another test conducted by researchers is the reliability test. Neuman (2016) states that reliability is the reliability or consistency of an attribute measurement. The reference used to see the adequacy of reliability using Cronbach's alpha values ranging from 0.60 to 0.70 or higher (Hair, Hult, Ringle, & Sarstedt, 2014).
Furthermore, testing the structural model (inner model) as a Hypothesis Test. Researchers do structural model or hypothesis testing to observe how a construct can relate to each other based on existing theories. In this study, the data analysis method used was structural equation modelling-partial least squares (SEM-PLS) using SmartPLS software. The advantage of using SEM-PLS lies in its reliability for estimating the nature of non-linear relationships compared to other test methods, which are only limited to linear relationships. The reference used by the researcher is the assessment of the path coefficient (β) and p-value, the coefficient of determination for each path (Hair, Hult, Ringle, & Sarstedt, 2014). Positive path coefficient values indicate that exogenous variables are positively related to endogenous variables, while for negative coefficient values, exogenous variables are negatively related to endogenous variables. The hypothesis in this study is said to be supported if the p-value <0.01 (significant at the 1% level), p-value <0.05 (significant at the 5% level), and p-value <0.1 (significant at the 10% level).
The purpose of data analysis using the PLS technique is to examine three research latent variables (e.g., perception of overqualification, job boredom, and counter social behaviour). The researcher also includes and examines the mediating role of KTP, which is based on the concept developed by Baron & Kenny (1986), which discusses the mechanism of testing mediating and moderating variables. The initial testing stage begins by directly testing the independent variable (POQ) against the dependent variable (PKP). Second, testing is done by testing the independent variable (POQ) against the mediator variable (KTP). Third, directly test the mediator variable (KTP) on the dependent variable (PKP). In the last stage, the researcher tested the independent variable (POQ) and the mediator variable (KTP) simultaneously on the independent variable (PKP).

Result
The study used primary data collected using a questionnaire through a survey method directly to the field. The questionnaire used by the researcher was developed and validated by the previous researchers. The original questionnaire used consisted of question items and was in English and translated into Indonesian to suit the research context in Indonesia. In addition, questionnaires were distributed to several Islamic Universities in Indonesia. By distributing questionnaires, it is possible for researchers to obtain a more significant amount of data and require a shorter time and relatively lower costs (Maksum, Handoko, & Fikriah, 2020). The results of the detailed data distribution can be referred to in the distribution table of the research questionnaire. Researchers use validity and reliability tests to test whether the research instrument can measure as good as the instrument that you want to study (Cooper & Schindler, 2014). Researchers use face validity and content validity to test the suitability of research instruments to the current research context and adjust the overall content, definitions and research constructs. Furthermore, the researcher also uses convergent validity and discriminant validity. The results of the convergence test of this study refer to the crossloading. For example, suppose the research items are grouped on the same variable and have a factor loading value greater than 0.70 and significant at the 1% level. In that case, practically, the measurement item meets the criteria for convergent validity.  Furthermore, the researcher also conducted a discriminant validity test in this study. The discriminant validity test was assessed based on comparing the Average Variance Extracted (AVE) and Cross Loading on each research variable. The purpose of testing discriminant validity is to confirm the correlation between research variables in the research model. The research model can be valid if the AVE score for each variable is equal to or above 0.5 and the cross-loading score is > 0.70 (Hair, Hult, Ringle, & Sarstedt, 2014). The results of discriminant validity testing in this study indicate that there is no correlation problem in each research variable because all variables achieve the required minimum AVE score > 0.5 and cross-loading score > 0.7. The results of the overall discriminant validity test can be referred to in table 3.  Table 3. This shows that all variables in this study have met the criteria for the discriminant validity test, which is based on the AVE score that reaches a score of > 0.5. In table 3, the KTP variable gets a score of 0.592, PKP gets a score of 0.571, and the POQ variable gets a score of 0.592. With the test results, it can be concluded that each variable used in this study has met the discriminant test. As for the cross-loading score, only a few question items meet the required score to meet the discriminant validity test. The KTP variable only has three question items that meet the minimum score, namely KTP3: 0.739; ID card5: 0.835; ID card6: 0.729. In the PKP variable, only six question items meet the minimum cross-loading score,   In the next stage, the researcher conducted a reliability test to test whether the research variables used in this study had met the reliability requirements. The research variable can be reliable if it refers to the Cronbach's Alpha value greater than or equal to 0.6 and the Composite Reliability score greater than or equal to 0.7 (Hair, Hult, Ringle, & Sarstedt, 2014). Hair, Hult, Ringle, & Sarstedt (2014) state that the coefficient value resulting from Cronbach's Alpha testing ranges from 0.5, indicating that the reliability of a construct is in the poor category but can still be used at the next level of analysis. Meanwhile, for the test score ranging from 0.6 to 0.7, it is included in the reasonably good category, while for a score of 0.8 or more, it can be categorized as very good. The detailed reliability test results can be referred to in table 5. regarding the reliability test. Referring to table 5. that all the variables involved in this study are declared reliable, following the achievement of the minimum score requirement of Cronbach's Alpha which ranges from a minimum of 0.6 or more and a Composite Reliability score of 0.7 or more (Hair, Hult, Ringle, & Sarstedt, 2014 ). For example, the KTP variable obtained a Cronbach's Alpha score of 0.653 and Composite Reliability of 0.812. In contrast, the KPK variable obtained a score of 0.850 and 0.889, and then the POQ variable obtained a score of 0.862 and 0.897. thus, each measurement item can consistently and reliably measure each research variable.
In the next stage, the researcher conducted the Inner Model test to test the research hypothesis. Researchers carry out testing of structural models or hypotheses to observe and confirm how a research construct can relate to each other based on existing theories. Researchers refer to the assessment of the path coefficient (β) and p-value and the value of the coefficient of determination (Hair, Hult, Ringle, & Sarstedt, 2014). If the path value is positive, the exogenous variable is positively related to the endogenous variable and vice versa. Researchers set the conditions for the support of the research hypothesis if, p-value <0.01 (significant at the 1% level), p-value <0.05 (significant at the 5% level), and p-value <0.1 (significant at the 10% level). The results of the Inner Model testing in this study can be referred to in table 6. Referring to the Inner Model test results presented in table 6, the R-Square value for the KTP variable gets a score of 0.021, which can be interpreted that the magnitude of the influence of the POQ variable on the KTP variable is 20.1%. In comparison, the remaining 79.9% is explained by other variables not involved in this study. While the R-Square value for the PKP variable reaches 0.412, which means that the magnitude of the influence of the POQ variable on the KPK variable is 41.2%, the remaining 58.8% is influenced by other factors not included in this study.
After testing the Inner Model, the researcher tested the research hypothesis by referring to the mechanism for testing the effect of moderation-mediation developed by Baron & Kenny (1986).  In testing the mediating effect, the researcher assumes that the output of the significance test parameter refers to the Total Effect table, not the coefficient table. The reason is that the mediating effect not only considers testing the influence between independent variables on the dependent variable directly but also has to consider testing through mediating variables (indirect effect) (Baron & Kenny, 1986). Thus, Total Effect is better if used to confirm predicting direct and indirect effects between research variables. Base on the Total Effects table, the T-Statistic value gets a score greater than 1.96, which means that the KTP variable fully mediates the indirect effect of POQ on PKP. With a T-Statistic value reaching 3,605 and higher than 1.96, P-Value 0.000 and Sig. of 0.001, thus hypothesis 2 has been supported.

Discussion
Direct Effects of Perceived Overqualification and Counterproductive Behavior Burris (1983) states that when someone works in a job that does not follow the qualifications, someone can experience frustration. Overqualification of an employee can increase the risk of counterproductive behaviour aimed at assuaging feelings of wasting their valuable resources (e.g., time, effort, and knowledge). The results of this study are consistent with the work frustration-aggression model from Fox & Specter (1999), which explains that a person can respond to events that make them frustrated by engaging in counterproductive behaviour. In addition, it also has an impact on a person's emotional state. When people feel that they are overqualified, they can trigger unpleasant emotional responses in their work environment, which in turn can lead to negative emotions such as excessive frustration, anger, job dissatisfaction, job hatred, and job boredom (Penney & Spector, 2008;Liu, Luksyte, Zhou, Shi, & Wang, 2014). The consequence of the emergence of various negative emotions is an employee's involvement in counterproductive behaviour.
The researcher integrates the theory of person-job fit to explain the impact that arises when someone has excessive qualifications in doing their job. Researchers argue that the perception of overqualification can have a positive effect on counterproductive behaviour (Liu, Luksyte, Zhou, Shi, & Wang, 2014). This is consistent with research conducted by Kim, Park, Shon & Lim (2019), which found that a worker who has a perception that they have excess skills, education, and experience in their work, can trigger negative emotions such as feelings of suffering, low well-being. Psychologically, low organizational commitment and ultimately engage in counterproductive behaviour. Someone who has higher qualifications than the job requirements can feel angry with their organization for not offering challenges in their work. The presence of negative emotions in the form of anger can then cause an affective reaction to the work situation, and in the end, counterproductive behaviour occurs. Based on this logic, the researcher can conclude that there is a positive and significant effect of POQ on PKP.

Indirect Effect of Perceived Overqualification on Counterproductive Behavior Through Boredom on Work
Based on the theory of person-job fit, P-J fit relates to the suitability or compatibility between a person and their job (Liu, Luksyte, Zhou, Shi, & Wang, 2014). At the same time, POQ is the perception of a person's skills, education and experience mismatch with their job needs (Penney & Spector, 2008). According to the literature, poor P-J fit can be associated with low job satisfaction, high turnover intention, poor overall performance, job boredom, and counterproductive behaviour. In addition, workers with poor job compatibility can lead to negative experiences such as job boredom (Kim, Park, Shon & Lim, 2019). When feeling bored with work arises, it triggers a person's perception that their abilities cannot be adequately used in their work.
Consistent with this statement, research from Luksyte, Spitzmueller, & Maynard (2011) found that there is a positive and significant influence between perceptions of overqualification, job boredom and the output, namely counterproductive behaviour. In addition, the boredom that arises is also caused by a lack of workload, lack of job challenges and lack of utilization of a worker's skills in his work. When a person feels that they are not appropriately used in their work environment, they can feel frustrated and depressed. Feelings of frustration and pressure that arise from a worker's perception can be referred to as negative emotions that lead someone to feeling bored with their work and ultimately lead to counterproductive behaviour (Kim, Park, Shon & Lim, 2019). With this logic of thinking, there is an evident influence of KTP as a mediator between POQ and PKP.

Conclusion
This research contributes to various literature related to the critical role of job occupations that explain the path of the influence of overqualified behaviour on counterproductive behaviour, and the P-J fit literature as a theoretical basis for explaining the phenomenon that causes a person to engage in counterproductive behaviour. This study shows that job boredom fully mediates the effect of perceived overqualification on counterproductive behaviour. The study results have implications for practitioners, that a high mismatch between skills, education, and experience with job requirements can harm the organization. Following the P-J fit theory, a high mismatch between worker qualifications and job requirements can trigger counterproductive behaviour. Thus, practitioners are expected to avoid a mismatch of abilities and job requirements for their employees to reduce the risk of counterproductive behaviour. At the same time, the implication for practitioners is that this research contributes to the enrichment of literature that discusses the critical role of job boredom as a mediating variable for the path of the influence of perceived overqualification on counterproductive behaviour.
However, the current research still has limitations, so it needs to be improved in future research. The first drawback is the limited use of research samples that only cover Islamic universities, and it is hoped that future research will cover a more comprehensive sample involving universities in general to produce mixed research results. Second, the researcher only uses the job boredom mediating role mechanism (KTP). It is hoped that future research can consider the moderating role of organizational citizenship behaviour (PKO) to confirm its effect on counterproductive behaviour. Third, the current study only uses research samples in the education sector, which have characteristics of low job demands, so they are less relevant to measure the effect of perceived overqualification (POQ) on counterproductive behaviour (PKP). Future research is expected to consider using research samples in the private sector, which requires higher performance demands than the education sector, so that the impact of perceived overqualification can be better investigated.
