Job security refers to the assurance that an employee will keep their job without the risk of becoming unemployed. It is influenced by factors such as the stability of the company, the demand for specific skills, and the overall economic environment. Employees with high job security often feel more confident and satisfied in their roles. In contrast, low job security can lead to stress and anxiety for workers, as they may fear layoffs or job loss. Industries that are growing, like technology and healthcare, typically offer better job security, while those facing decline, such as manufacturing, may present more risks for employees.
