What do you do when you're job-searching, you get the interview, you get hired, then you realize that this is the last place in the world you want to work? What if you hate your new boss, or your workplace? What if it looked good at first, but now that you're there, you see trouble? How do you quit before you start? Should you give it a chance? Should you work the job until something better comes along? How do you handle your exit and still leave on good terms?
