Not sure how to word this, and will probably make me sound paranoid but I'll try.
I have recently been promoted, after years of hard work and high performance. I am stoked! I manage my own team of 10 people, its a slightly different role/team to my old team but still the same area of the business.
My old boss and I are now part of the same management team, we are the same level. But they seem to be struggling to see me go from their subordinate to their peer. They make jokes at my expense during management meetings and ridicule things I suggest even when our boss thinks it's a good idea. But everything is done in an "only joking" way so no one seems to see how mean it feels to me.
I'm trying to find my way, build up my new team to get higher performance and yes learn to be a line manager but I feel they keep trying to knock me down and make me feel stupid. Comments like "you'll get the hang of this one day" when I make a suggestion or dissing my team members even though theirs are underperforming a lot and mine are not as bad (still not great but I've got a plan in place for this).
Also comments about how they have so much more work than I do, and when I offer to help (and am quite capable to do so) laugh at me and say I must not be very busy then. I am, but I also believe in sharing the workload.
They are only like this with me, and not the other 6 members of the management team. I am the only one who has been promoted upwards from under this person. I'm also the only woman in a management team of men, so feel like I have to work harder to be taken seriously.
Currently I tend to ignore it, or try laughing along so as not to show I'm upset by the comments as I don't want to be seen as weak. But I am upset.
