In my perspective, international companies, because of their global presence and strict labor laws, adhere to the labor laws of the local government, both in their parent country and the country of their presence as a branch/subsidiary. Few Indian companies with a global presence also have similar processes, but these often get diluted when there is no proper execution. (Benchmarking: Many small companies seem to follow or get inspired by these global leaders in their HR policies.)
Indian companies, when acting as a subsidiary, will normally receive notifications on many things to match their HR standards. The HR policies, again, may have to align with their established standards, while actual Indian companies may have to stand on their own.
This discussion can be made more interesting if others contribute their opinions.
