The Payment of Gratuity Act provides social security for employees by requiring employers to pay gratuity to employees who have worked for at least 5 years upon superannuation, retirement, death, or disablement. Employers must obtain insurance to cover their gratuity liability and pay gratuity within 30 days, or pay interest on delayed payments. The Act applies to factories, mines, plantations, ports and other establishments with 10 or more employees.
