I recently won an award in my department for excellent performance and so on. I have no idea if anybody else won one, my manager just messaged privately. It was a monetary award, and I haven't told anybody else.
I've told one friend who's in a different department and that's it. It's not like I would go around bragging or something, and I think most would genuinely be happy however I think some people would rightly question, why didn't I get one?
Maybe some others got one, but so far nobody's said anything. I don't see a situation in which it could be revealed unless my manager brought it up in front of others.
I feel I earned it and deserve the award, but AIBU to keep quiet?
