Abstract:
The primary objective of this study was to investigate the relationship between perceived organisational support, frustration with work and occupational commitment among public secondary school educators in the Sedibeng West District. The social exchange theory, expectancy theory and side-bet theory constituted the bedrock in this study.
In order to achieve the primary objective, a quantitative research approach was adopted, and a descriptive survey research design was utilised. The reliability of the measuring instrument was confirmed satisfactory, and thereafter the questionnaires were self-administered to three hundred and seventy-three educators, HODs, deputy principals and principals at nine public secondary schools using a convenience sampling technique. Two hundred and forty questionnaires were retrieved, constituting 64.3 percent response rate, and the data obtained was analysed using the Statistical Package for Social Sciences (SPSS) 25.0 and the Analysis of Moment Structures (AMOS) 25.0 for statistical analysis.
The statistical analysis performed include descriptive statistics using frequencies, mean and standard deviation. Inferential statistics was utilised to determine the relationship between the two factors of perceived organisational support, frustration with work and occupational commitment. The inferential statistical methods used include Pearson product moment correlation coefficient, confirmatory factor analysis, path analysis and structural equation modelling.
Confirmatory factor analysis (CFA) was conducted to confirm the factor structure of the constructs in the study, and to determine if the data fit the model. Six model fit indices were used to assess the measurement and structural model fit assessments, which include Chi-square value over degree of freedom (χ2/df), Goodness-of-fit index (GFI), Root mean square error of approximation (RMSEA), Norm fit index (NFI), Tucker Lewis index (TLI) and Comparative fit index (CFI). The results of the model fit indices indicated a satisfactory fit of the data with the measurement and structural models. Thereafter, path analysis was performed on the research model to measure the path coefficients in the research model.
Structural equation modelling (SEM) was applied to test the hypotheses and the results revealed that there was a significant negative relationship between the job-related factor and frustration with work; a significant negative relationship between the relationship factor and frustration with work; a significant negative relationship between frustration with work and occupational commitment; a significant positive relationship between the job-related factor and occupational commitment; and a non-significant positive relationship between the relationship factor and occupational commitment.
The correlation analysis also showed that there was a moderately significant negative correlation between the job-related factor and frustration with work; a moderately significant negative correlation between the relationship factor and frustration with work; a strong positive correlation between frustration with work and occupational commitment; a moderately significant positive correlation between the job-related factor and occupational commitment; and a moderately significant positive correlation between the relationship factor and occupational commitment.
The reliability of the measuring instrument in the main study was tested using Cronbach alpha coefficient and composite reliability, while the validity tests were confirmed using face validity, content validity, construct validity, convergent validity, predictive validity and discriminant validity.
Based on the findings, recommendations were proposed to enhance the perception of organisational support among educators, HODs, deputy principals and principals; reduce the level of frustration with work; and foster increased level of commitment to the teaching profession.
