Yes, but saying that the purpose is to be "casual" as an explanation sounds a lot better to the employees who are listening to it than saying that the purpose is to be "submissive", which is what kneeling before the person you are taking orders from really is.

Not in America. It's supposed to mitigate the natural inferiority imposed from looking up at someone.

IMHO, someone standing and addressing you while you sit comfortably is the opposite.

I'm an American. And usually if they're on their knees, they're looking up at you. At least when they were the ones looking down, they had the plausible excuse of having to move around all the time.
