My boss has several favorite people in the team. He tends to show it when he doesn't like somebody clearly.
I've now fallen out of grace. I was in his inner circle when I joined 6 months ago, now I'm very much out.
I didn't do anything awful. He gave me an undoable task - he's known for doing that - and I tried to diplomatically convince him it can't be done. He does that a lot, e.g. tells me he doesn't want me to work overtime and then tells me he expects me to implement 3 new projects still this year.
I have voiced a question which he interpreted as critical during a (internal) meeting ("maybe we could... instead"). He reacted very badly to that. I explained myself later, apologized if it came across as critical. I admit, it's possible I chose the wrong tone for the question. I was frustrated because of the crazy work time and lack of progress despite discussions.
He's a very political person, is doing everything possible to be liked by his peers and bosses, which in the past meant not standing up for me when that was important.
Why do I think I've fallen out of grace? He ignores my contributions. He criticizes strongly my deliverables, although I have had objective successes in the last weeks and have been working very hard. He ignores most of my emails.
Is there a way to make it better or should I start searching for a new job? The truth is my boss is known for being difficult. But some people get along with that well and I wouldn't like to switch my job so soon.
