The effect of job insecurity and work overload on outsourcing employee performance with job satisfaction as a mediating variable at PT. Swabina Gatra Gresik

This study aims to analyze the effect of job insecurity and work overload on employee performance through job satisfaction as a mediating variable at PT. Swabina Gatra Gresik. The research background stems from the phenomenon of suboptimal performance among security personnel, which is suspected to be influenced by job uncertainty and excessive workload. These conditions create   psychological pressure, reduce motivation, and ultimately lower both job satisfaction and performance. The research employed a quantitative approach by collecting data through questionnaires distributed to 108 outsourcing employees at PT. Swabina Gatra Gresik. Data analysis was conducted using the Partial Least Squares (PLS) method to examine direct and mediating relationships among variables. Validity and reliability tests were also performed to ensure the accuracy of measurement within the research model. The results showed that job insecurity had a significant effect on employee performance, whereas work overload did not significantly affect employee performance. Furthermore, job satisfaction significantly mediated the relationship between job insecurity and employee performance, but did not significantly mediate the effect of work overload on employee performance. These findings highlight the importance of managing employees’ sense of job security to enhance satisfaction and performance, while workload management requires further attention to maintain balance and efficiency among outsourcing employees.
