How to handle fucking management assholes playing politics in office. Always there to take credit of the job they haven't done.
Really pissed off !!!

Fuck them back?

Welcome to the wonderful world of office politics.

Slowly undermine them from within. But do it discretely. There is a good chance other people already hate them. Just bring them into the fold. Finally, mutiny as a group. There is much power in numbers. If you have a few years to waste on this it's pretty entertaining even if it doesn't go your way.

Or just forget about it and move on. Probably the more sane option...
