Investigating the Perception of Public Sector Higher Education Institution Faculty Members about the Influences of Psychological Contract on Organizational Commitment

The core aim of this research study is to investigate the consequences of psychological contract on organizational commitment. The context of the study is higher educational Institution International Islamic University Islamabad. Data is collected from 90 faculty members of International Islamic University Islamabad through questionnaire by using the convenience sampling approach. The alpha index is using minimum (0.60) to measure the item reliability. Regression analysis indicates that psychological contract is positively and signif-icantly associated with affective commitment (0.55), continuance commitment (0.74), and the normative commitment (0.69). From the findings, it is concluded that psychological contract is very important for organizational commitment. Higher degree of psychological contract has a result of more organizational commitment. This paper recommended that higher educational institutes should focus on developing a positive and healthy psychological contract with employees. Failure to do so may result in unhealthy psychological contract and can produce negative employee related outcomes.


Introduction
Higher educational institutes have high importance for any country because of their role in socio-economic and human resource development of any nation. Pakistan being a developing country also cannot deny the importance of higher educational institutes since if these higher educational institutes play their role properly, then it can increase the process of development. In higher educational context, the human resource play very important role since good staff especially faculty is mainly the source of competitive advantage and if work hard, then can bring high impact on the student life. In this regard, the faculty psychological contract is an important concept. Psychological contract is exchange relationship between employer and employee. Organizational commitment which is another related concept is also important for developing good employee performance and other favorable outcomes. Without having enough organizational commitment among the staff, staff may not be interested in the work and may leave organization as get a new chance.
Generally, private sector institutions experience high staff turnover which seriously reduces their performance and market image. In this regard, psychological contract can provide a useful lens for understanding employee turnover as well as can be used as a useful tool for retaining staff. When employee perceives that their psychological contract is violated by the organization, so they may perceive dissatisfaction and injustice, and may start thinking about leaving the organization. In current research, the focus is on understanding organizational commitment from psychological contract point of view and investigating the relative dependence of organizational commitment of psychological contract. Past studies show the positive aspects of having a strong or positive psychological contract on employees. These favorable outcomes include job satisfaction, work satisfaction, and so on. For example, job stress is also found to be predicted by psychological contract [1] (Bocchino, Hartman, & Foley, 2003). Further, the relationship between psychological contract and organizational commitment is also found in previous studies [2] (Gumusluoglu, Karakitapoglu-Aygun, & Hirst, 2013) [3] (Eslami & Gharakhani, 2012). For example, study conducted by [4] ( Lemire & Rouillard, 2005) investigated the relationship between psychological contract violation and organizational commitment in the context of civil servant employees in a Canadian federal organization. The findings are that psychological contract and commitment is positively associated; while, psychological contract violation is related with contract violation and intention to leave the organization. Another study conducted by [5] (Sturges and Colleagues 2005) investigated the role of psychological contract in career management behavior and help. The findings are that psychological contract fulfillment result in positive job performance and organizational citizenship behavior, while, its violation result in employee intention to quit and other unfavorable workplace behavior. Based on the past studies findings, we are going to investigate the relationship between psychological contract and the organizational commitment in our settings. The hypothetical model is given below which is mainly based on the social exchange theory. According to the social exchange theory states that social relationship is based on exchange [6] (Atkinson, 2006). Here it is important to mention that social exchange is not simply a single theory, rather, it is a large set of theories or general framework used in several social and organizational related studies. The social exchange theory supports our model in such a way that it can be successfully used as a lens to understand the psychological contract and employee outcome (commitment) as an exchange relationship. If employers fulfill responsibilities, employees are likely to perceive fulfillment of psychological contract and produce favorable outcomes in return. On the other hand, violation of psychological contract will result in unfavorable outcome.
Finally, this research paper examines the relationship and influence of psychological contract on organizational commitment in term of its three components. Typically, higher education institution faculty members are in consideration for research. The ratio of research on this topic for government institutions is low. It is expecting that this paper fills the gape of research for public sector higher education institutions especially IIUI for this topic. Psychological contract is taking as an independent variable and research is focusing to find its relative influence on Affective Commitment, Continuance Commitment and Normative Commitment.

Problem Statement
This research paper associated with its core aim to investigate the effect of Psychological contract on organizational commitment. It is a research gape to work on "Influences of Psychological contract on organizational commitment" for public sector institutions like IIUI. The employees of government sector institutions are not mainly focused by the researchers. At the end of testing the hypothesis, this research paper providing facts about the association of Psychological contract with organizational commitment of the faculty members of a public sector institution. Furthermore, this research study finds either the Psychological contract has positively influence the organizational commitment or not.

Literature Review
This section provides review of literature on employee psychological contract and employee organizational commitment.

Psychological Contract
Psychological contact is employee understanding and perception of the exchange relationship between what employees gives to the organization and what the organization gives in return [7] (Cassar & Briner, 2011). Psychological contract also refers to the beliefs an individual held related to the implicit terms of agreements between individual and his/her organization [8] (Rousseau, 1995(Rousseau, , 2000. The psychological contract can be classified in to two aspects including transactional and relational [8] (Rousseau, 1995(Rousseau, , 2000. The transactional contract is based on the satisfaction from both sides based on the material benefits. The relational contract is based on the satisfaction gained from both sides based on social affection. When employee feels that their agreement (psychological contract) between them and organization is fulfilled, it results in increased job performance and other favorable outcomes [5]  Another study conducted by [10] (Robinson and Rousseau, 1994) examined the relationship between psychological contract violation and different outcomes. Their findings were that when psychological contract is violated, it associates negatively with violations and trust, satisfaction, and intention to remain within organization. Another study conducted by [11]

Organizational Commitment
Organizational commitment is the employee's psychological perception of the relationship between individuals and organizations and it reflects employee psychological status of being loyal to the organization [13] (Meyer and Allen, 1991). Organizational commitment is about psychological status between employees and organization. Organizational commitment is important since it result in employee's intention to stay or leave the organization. The three dimensions of organizational commitment are affective commitment, normative commitment, and continuance commitment [13] (Meyer and Allen, 1991). The three components model of organizational commitment given by [13]  with the pairing of affective commitment leads to several favorable employee related outcomes and behavior [14] (Gellatly, meyer, & Luchak, 2006). Relationship between organizational commitment and intention to stay is also established in previous studies [15] (Wasti, 2005;Glazer & Beehr, 2005). Relationship between organizational commitment and job satisfaction is also established in past studies [16] (Clugston, 2000). Employees are more jobs committed if they have perception that organization is being working also for their interests [17] (Kamran Nawaz, Mudassar Usman, 2018). The employees who are emotionally attached with the organizations have more degree of work commitment. Beside on working hours, such employees work for organization at their highest level [16] (Clugston, 2000). If an organization have less degree of person-organization fit than the employees are not creative and nor performs the tasks in best way. In this situation, workers are not emotionally engaged with their works. Therefore, employees either want to leave the organization or being fired by institutions.
This situation negatively affects the continuance commitment of employees [17]  The proposed hypothesis is for this research work:

Research Methodology
This section is providing details on research methodology adapted for conducting the current research study. Details regarding different aspects of research methodology are as under.

Population and Sampling
The study is conducted at International Islamic university Islamabad. The total employees in this organization are about 500. Based on the sample size calculator table provided by [21] (Bartlett, Kotrlik, and Higgins. 2001) the required sample size is 90. Sample will be drawn across the academic staff Lecturers, assistant professor, associate professor and professors at the university through convenience sampling technique. Structured closed ended questionnaire will be used as main method of data collection.

Data Collection and Instrument
This research is consisting of three parts. First part is about basic demographic questions. Second part is used for measuring psychological contract adapted from [10] (Rousseau, 2000). The measure is based on two dimensions including perceived psychological contract by employer and perceived psychological contract by employees and consists of 4 items. Organizational commitment is measured by measure adapted from [13] (Meyer and Allen, 1991). In this measure, there are 8 items for measuring affective commitment, 8 items for measuring normative commitment, and 8 items for measuring continuance commitment.
Reliability test is applied by following the minimum criteria of 0.60 for acceptance. The value of alpha is above than 0.60 so it is reliable for research.

Results & Discussion
The following chapter intends to provide results and discussion. Figure 1 shows the model for research with both variables. As Figure 1 is showing the psychological contract and effect on organizational commitment of employees whereas,   Table 1 showed the participants with respect to gender. There were total of 65 male and 25 female respondents. The higher proportion of male participation in the research is due to the higher number of male workers in the selected organization. Figure 2 also shows the blue as a majority which is for male respondents as well.       Table 4 shows the value of reliability alpha for the variables. Psychological Contract is measured by 4 items with value 0.61. Affective commitment is measured by 8 items with value of 0.762. Continuance and Normative Commitments also measured by 8 items with alpha values of 0.72 and 0.814 respectively.

Descriptive Statistics
Descriptive statistics for the variables in the study are given below.

Regression Analysis
Regression analysis is used for testing the relationship between psychological  Table 6 shows the regression results for the effects of psychological contract on affective commitment are given in the table above. R value indicates that psychological contract and affective commitment are 55.7% positively associated.

Regression Analysis for Affective Commitment
Further, the R square value indicates that psychological contact explains 33.3% change in the dependent variable of affective commitment. The beta value shows that one unit increase in psychological contract will bring 0.482 increase in the affective commitment and the relationship is significant (t > 2). The F statistics suggest that model is fit and significant (Fstat = 43.918, P < 0.05).    Table 7 shows the regression results for the effects of psychological contract on continuance commitment are given in the table above. R value is describing that psychological contract and continuance commitment is 74.7% positively associated. Further, the R square value represents that psychological contact explains 55.8% change in the dependent variable of continuance commitment. The beta value shows that one unit increase in psychological contract will bring 0.629 increase in the continuance commitment and the relationship is significant (t > 2). The F statistics suggest that model is fit and significant (Fstat = 111.111, P < 0.05). Table 8 is showing the regression result for the effects of psychological contract on normative commitment is given in the table above. R value shows that psychological contract and normative commitment are 69.5% positively associated. Further, the R square value is showing that psychological contact explains 48.3% change in the dependent variable of normative commitment. The beta value shows that one unit increase in psychological contract will bring 0.656 increase in the normative commitment and the relationship is significant (t > 2). The F statistics suggest that model is fit and significant (Fstat = 82.302, P < 0.05).

Discussion on Results
The objective of the study was to see the effects of psychological contract on employee commitment in the context of higher educational institutes. The hypothetical model showing in Figure 1 explains the aim of study. For this purpose of analysis, a single university is selecting, and data was collected through survey questionnaire. The findings indicate that psychological commitment is having positive and significant effects on employee's affective commitment, continuance commitment, and the normative commitment.  (Rousseau, 2000). Thus, it can be concluded that psychological contract result in favorable outcomes including employee commitment.

Conclusion
The core purpose of this research paper is to investigate the influences of psychological contract on organizational commitment of employees. Psychological contract is measured through 4 items developed by [8] (Rousseau 2000). The three dimensions of organizational commitment, affective commitment, normative commitment and continuance commitment is measured through [13] (Meyer and Allen, 1991). This research paper confirms the positive influences of psychological contract on affective commitment, normative commitment and continuance commitment. If employer seems to be fulfilling his/her responsibilities, employee will perceive it favorably and may in return work for positive outcomes such as performance or be more committed. On the other hand, if psychological contract is violated or expectations are not fulfilled, then employee's commitment may be decreased which may lead to unfavorable outcomes. In higher educational context, thus, maintaining a healthy psychological contract is very important as it will help universities and other higher educational setups to retain staff. Having a poor psychological contract with the staff will result in high turnover among faculty which will undermine the performance and goodwill of the universities.
Thus, we can conclude that psychological contract is very important and have significant positive influences on employee commitment so this concept especially in higher educational context should not be ignored by the management.

Limitations and Future Research Directions
The limitations of the study are that it only focused on one aspect which was the psychological contract and employee commitment. Other relevant aspects were excluded. Further, the sample size is small and only drawn from single organization which is also its limitation. This research paper discussed the influence of psychological contract on employee commitment, but many other factors will also important for employee commitment neglected. Psychological contract is . This is expecting that this will paper help researchers and organizations for understanding of relative impotence of psychological contract. This is also expecting that other factors like organizational justice, person-organization fit which play role for job commitment of employees will research by researchers and scholars.
