I would appreciate any advice, even if that advice is to just do nothing.
The situation is the following. I’ve been on a detail away from home for 50 days, out of a total of 60 assigned, working for a different agency. (Not going to say which agency.). Today I was in an impromptu meeting with my detail supervisor who, for reasons I can’t explain, would continue to speak to me, and my colleagues, with condescension about the work we had completed. He was very behind in reviewing work, and was asking me detailed questions about work I had done three weeks prior.
In addition, this supervisor has done a tremendously poor job of training those of us on detail, and has frequently provided contradictory training materials. I have exceeded at the work and have made all the changes he’s requested, but he would still knit pick at our work (I’m not the only person from my agency on detail). Regardless, after several minutes I finally told him I didn’t appreciate being spoken to with such condescension. I’m the same GS level as him, more years of service than him, and frankly a better supervisor than him. He immediately became agitated and aggressive. I told him I very much wanted to do good work and impress him, but he would not listen. He eventually said I could leave his office, which I did. There was no point in further efforts to work with him.
I received an email less than an hour later that my detail was ending in one day, with nothing from this agency’s management. Just notice that I’m done. It’s honestly incredibly insulting and hurtful as this paints me in a terrible light back home. My office and management knows me, but there’s also no way this doesn’t have some unanticipated affect on my future career. I’m angry, but keeping it professional. I just don’t know if I should do something, what that something would be, or whether anything else is worth doing.
The funny thing is that I’m ready to go home and be done with this situation. I do worry for future participants though. Regardless, thanks for listening.
