I don't know if I'm overreacting here.
On Friday evening I worked past my hours to deal with what was a potentially challenging / contentious issue that had arisen that day. It caused me a lot of stress but no one else from my team was around to bounce anything off on Friday, so I dealt with it the best I could by myself. I then emailed the relevant colleagues on Friday evening who needed to know what had happened and how I'd dealt with it, so they'd be appraised of the situation.
I don't work Mondays but I logged in today just to see what I'm going into tomorrow. I'd had a reply from one of the senior members of the team (not my direct line manager but senior in the organisation) basically reprimanding me in what feels like a shitty way for one small aspect of how I dealt with the situation, ignoring the fact I worked past my hours to deal with the entire situation myself. She also hadn't commented on the issue itself really, she's just offered a criticism of one small aspect of how I dealt with it (which I also happen to disagree with her on). My main gripe is not that she disagrees with my approach as such, but that her reply was unnecessarily shitty and there was no thanks for dealing with the situation, and on top of that she "sent to all" instead of just me, so this now essentially feels like a public telling off via email as 5 other members of the team are copied in. I feel she could have more sensitively communicated her disagreement with the small aspect she has chosen to comment on, for example by just raising that part directly with me.
The upshot is I now feel anxious to go into work tomorrow because I am angry about the way she's handled it and don't particularly want to face her (she's not the most approachable person at the best of times), and also I just don't get paid enough to work past my hours on a Friday to give a shit about issues that might affect my team, to then receive basically no thanks and just criticism instead.
AIBU?
