> The problem - Anger management, blames people for things when they go wrong. Unreasonable work expectations for product features and expectations that a person would be available anytime/any day weekends including to do work and support. Does not pay properly or on time. Does not communicate properly on what is happening at the high level. In short, someone for whom you will find it hard to work for even if you like the problem the company is trying to solve and doing your best for its success.

Have you raised this to him/her? My two cents: raise all the points along with one or two advices, this way she/he won't feel attacked but rather helped.

You may end up quitting if you're not satisfied with the reaction but at least you will have tried to fix it.
