There are at least three methods being followed. The obligation on the part of management is to provide a canteen facility, whereas how it should be run is left to the management's option.
Run the canteen on its own
1. Provide everything from A to Z, including staff, equipment, provisions, and implement menus. It should not be a profit center, charge nominal prices for items, or even be fully free but remain as a welfare measure. This is suitable for large units or factories.
Outsource operations
2. Provide infrastructure and equipment but outsource operations. Finalize menus, fix rates, ensure quality and quantity of items, and provide subsidies or pay bills at fixed rates as per quotes.
Managed by employees' union
3. Let the canteen be managed fully by the employees' union or their welfare society to be run on a No Profit, No Loss basis. Infrastructure is to be fully provided by the management.
Fully outsourced
4. Engage catering contractors to supply items on fixed menus finalized in consultation with employees. Bills are paid by the management.
Nowadays, most IT/ITeS run cafeteria-type facilities providing tea/coffee, light snacks, etc., in their automated vending machines, meeting the costs and offloading food and fruit supplies.
As long as management provides a decent canteen facility, unions will have no issues. Also, go through this link -
