Thank you dmc123,
The company has its headquarters in Mumbai, but other branches exist in other states also, so the laws pertaining to those states will aply in the respective branches or will they remain the same as the head office's. And is 'Maharashtra mathadi, hamal and other manual workers act' applicable to establishments also or only to factories?
