What is the size of the factory?
How many employees?
What kind of budget is being planned for welfare?
Sustaining additional welfare facilities is equally important.
Once you start something,stopping it may be difficult,so keep all aspects in mind.
Factories Act itself spells out some conveniences to be provided-hope those are provided?
Making those facilities like canteen,creche etc more attractive and wide ranging facilities itself will not alone meet legal compliances but add to welfare.
Please tell what have you planned from your side?
Make your post more descriptive and explanatory.
Members will definitely give valuable suggestions which will add value to welfare services.
