Industrial Relations And Labour Laws
As your question states it clearly that Outsourcing of a canteen will be done to a Third party--NGO /a cooperative society, then in such case, none of the above compliances applies to it.
Whenever, a specific unit of said company is outsourced to third party, then in such case, third party takes care of it.
Hope you are clear now.
