I feel like non consensual anything adds stress. One of my least favorite things is being hugged by people I work with and I always feel awkward turning down a co worker.
I am not a germaphobe at all (I'll eat food off the floor if it falls), and I agree 100%. The non-washing of hands is endemic.
Fist bump to the rescue!
"I've got a cold, and you don't want it. Fist bump?"
Ugh
I get the impression that they were on the receiving end of the hugs :)
I've never been in a position to have to turn down a coworker's hug (thankfully), it seems very odd indeed. Like the GP, I woudln't engage in that sort of physical contact with coworkers.
