While it IS true that Western bosses here can be just as bad, taking advantage of the situation just as Western smokers might of lax smoking prohibitions to light up in restaurants without restraint, in general Western bosses heads aren't so far up their arses.
Beware the Chinese boss.

As sb who left no boss to come to China initially for a job, I was determined to stick it out irrespective of the negative aspects of the culture shock. Though the accommodation was sometimes not so good, it was adequate and, more importantly, rent-free. After 3 years without a job back home, I was extremely happy to get a job teaching English in China.
Chinese bosses regard themselves way above their employees, true enough. But this is more than compensated for by the great respect that the young learners of English here have for their foreign teachers.
As for smoking, I'll do as the Chinese do. At the school I'm presently teaching at, the Chinese teachers smoke on campus, me too, that's my right!
