The document discusses the Payment of Gratuity Act of 1972 in India. It defines gratuity as a monetary benefit given by an employer to an employee who has worked continuously for 5 or more years upon retirement. Gratuity is meant to help employees financially after leaving employment. Continuous service is defined as uninterrupted even with periods of leave, sickness, layoffs, etc. The Act applies to establishments with 10 or more employees, including factories, mines, ports, shops and plantations. Gratuity is calculated based on last monthly salary and years of service, and differs from provident funds which require contributions from both employer and employee over time.
