Employee welfare refers to efforts by employers to improve workers' living standards and well-being beyond legal requirements. It includes various services, benefits, and facilities like drinking water, toilets, crèches, medical aid, housing, education, and recreation. Agencies involved in employee welfare are central and state governments, employers, trade unions, and other organizations. The law mandates certain welfare facilities under acts like the Factories Act, Mines Act, and Contract Labour Act. Labour welfare officers advise on welfare, provide services, supervise facilities, and mediate between workers and management.
