Is hugging completly off-limits in the workplace?

There is a Xing newsletter and sometimes they really draw attention to interesting articles. It seems a bit strange in times of me too discussions and times where managers avoid being alone with just one employee in the elevator to ask if hugging is completly off-limits in the workplace or not. But it is also a cultural problem. For some societies it might be remarkable to have physical contact and in others it is not because it is part of the communication system and the welcoming. Are you interested to discuss the situation at your library or in your country? I would love to receive your comments.
