I received multiple job offers which differ hugely in compensation scale (up to 2x). Should I reveal the numbers for further negotiation? Should I hang in with my part-time job, that I like, which has no hope of full-time, and cut corners to the bone, in hopes of finding a job that I am not dreading, or give up the PT job in hopes that a job I was just offered isn't as bad as I am making it out to be?
