I have no first hand experience but from what I have heard from cousins etc. , it is true that bosses in India in private sector delegate you more work and expect you to work like dogs thinking about your family last. Reminds me of an incident when my bro was working more than 12 hrs a day to meet some deadline and one evening around 9 PM he went to a nearby PCO to call his home and met his boss there, and his boss aked him what he was doing here, he should be at work and when he said he came to call his home, he said whatever, do fast and get back to work. He was utterly pissed off.
That is what I usually hear from friends in India too that they or their husbands have no time for their family.
But in US also, if you have a desi boss there are chances that there will be politics and chamchagiri specially if your boss has worked in India and gone through it. But it usually isn't that bad.
Best I have heard is Europe where people take 2 hr lunch break and have a nap and leave at 5 sharp. Nobody forces you to work more than that and you are never under pressure.
