In the dynamic environment of the Indian IT sector, job insecurity has emerged as a critical challenge affecting the well-being of employees. This study investigates the impact of job insecurity on the work-life balance (WLB) of IT professionals in Coimbatore, a rapidly growing tech hub. With increasing layoffs, contract-based employment, and project-based hiring trends, IT workers face heightened uncertainty, which may lead to stress, reduced job satisfaction, and difficulties in balancing professional and personal life. Data for this study was collected through a structured questionnaire using a convenient sampling method among IT employees in Coimbatore. The findings provide insights into how job insecurity is reshaping work-life dynamics in the IT industry, offering implications for employers and policymakers to mitigate these challenges.
