A certain co-worker of mine has a habit of placing his foot on my desk while conversing with me. My desk is an L shape and where he stands is not across the desk from me, but at the end of one of the legs. This makes me uncomfortable uncomfortable as his crotch is at a relatively close distance to my face. I cannot roll my chair back too far because the other leg of the desk and a wall are behind me.
The situation is further complicated because I am a woman and he is my direct superior. I honestly believe that he does not know it makes me uncomfortable. Nor do I believe there is anything sexual about the behavior. He is in his late fifties and I really think he is just used to a different 'time and place'.
I realize the most honest solution would be to directly confront him about the issue but in the past when I have done this it always results in this odd period that can last for days where he acts like he has been offended, mopes around, and generally avoids me.
I live and work in the US.
My questions are: Is it appropriate for someone to place their feet on your desk when speaking to you? Is it appropriate for a supervisor to place their feet on a subordinate's desk?
Any advice on non-verbal ways to indicate that this is an uncomfortable physical setting are greatly appreciated as well.
Thanks,
