I went back and reread the DIAD message and I believe you are reading way more into it then what is actually there.
I'll ask again, would you think it's fine to replace man with Hispanic, black, white ect?
You may come from a way of life where it's okay to be sexist, lots of us did or do, doesn't make it okay.
Lots of people would probably believe the guys read way too much into the safety demonstration where it could appear that a doll was being hanged. Guess what, they felt offended, sued ups and won a lot of money.
People have different opinions of what's wrong and right. Imho if there is any gray area or you think somebody might take this the wrong way, as a person in management..... YOU DONT SAY IT. Simple.
Corporations can't talk like me and you can... I think your misconstrueing that fact. The center manager represents ups management and how their treat employees.
