Under Sections 16 to 19 of the Contract Labour (R&A) Act, 1970, every contractor employing contract workers must provide the following welfare facilities: (1) Canteen facilities where 100 or more contract workers are ordinarily employed; (2) Rest rooms or halting accommodation where workers are required to halt at night; (3) Drinking water facilities within a reasonable distance of any place of work; (4) A sufficient number of latrines and urinals of the prescribed types; (5) First-aid boxes with prescribed contents. The critical point for principal employers: if a contractor fails to provide any of these facilities, the principal employer is legally obligated to provide them and may recover the cost from the contractor. This is one of the key principal employer liability provisions under the Act.
