More of a WWYD
I'm in my early 30s and last year a man in his mid 20s joined our company. We've always gotten along very well and I was puzzled when other female work colleagues said they didn't like him and found him patronizing.
But then this summer he trained me to do some new tasks as I'm shifting roles slightly and ever since then he has started speaking to me like I'm a complete idiot. Things like "Do you understand? Are you following? You don't have to say yes if you don't understand you know", asking if I have written my notes in a way that I will later understand (it was shorthand), expressing great surprise that I managed to get a task right the first time and basically doing a Ross Gellar impression with his hands "I would have wanted you to be up here at this point but you're actually down here" then telling me "that's not what he meant" when I said I was happy to start doing the tasks unsupervised if he felt I should be doing so by this point. FYI I started doing the work without him checking after that and have managed just fine.
It's like since he trained me the dynamic has shifted and he now has no respect for me. He must be aware on some level that he's doing it because there are senior (or male) members of staff that I know he wouldn't dare speak to like that. I've spent the whole Christmas stewing about it but I feel that if I say something it will make things awkward and we have to work together in the same department (it's a small company). FYI it's not at all that I have a problem with a younger person being more knowledgeable than me - I'm happy to learn from him but I don't want to be spoken down to like that. How would you handle this?
