better the devil you know than the devil you don't
Proverb meaning that a familiar but unpleasant person or situation is preferable to an unknown one that might be worse. Literally: 'rather than a Buddha you don't know, a familiar ogre'.
The new boss is strict, but as they say, better the devil you know than the devil you don't, so maybe I'm fine with the current situation.
