Abstract
This study examined the effect of job sharing on organizational commitment among employees in selected Level 4 private hospitals in Mombasa County, Kenya. The study was guided by Spillover Theory and adopted a cross-sectional research design. The target population comprised 1,143 employees, from which a sample of 296 respondents was selected using purposive sampling for the hospitals and proportional stratified random sampling across employee categories. Data were collected using structured five-point Likert-scale questionnaires, with a pilot study involving 30 respondents at Beyond Scope Hospital. Data were analyzed using SPSS Version 27 through descriptive statistics, Pearson correlation, multiple regression, and diagnostic tests at a 0.05 level of significance. The findings established that job sharing had a positive and statistically significant effect on organizational commitment, with a beta coefficient of β = 0.308 (p < 0.05). This finding led to the rejection of the null hypothesis, confirming that job sharing significantly predicts organizational commitment among employees in the selected Level 4 private hospitals. The study concludes that job sharing enhances organizational commitment by providing employees with greater flexibility, promoting work-life balance, improving employee well-being, and supporting fairness in work arrangements. The study therefore recommends that private hospitals strengthen job-sharing practices through clear policies, equitable workload distribution, employee consultation, and effective scheduling to enhance organizational commitment while maintaining quality healthcare service delivery.
