The term "Ghost Workers" refers to employees who are on a company's payroll, but do not actually work for the organization. They may have been hired in the past and continue to receive salaries or wages without performing any current job duties. This can occur due to various reasons such as downsizing, restructuring, or errors in human resource management systems. The term "ghost workers" is also used to describe individuals who are paid for work they do not actually perform, often through fraudulent means.
