If you've been in the business long enough, then you've experienced situations that made you upset, angry, irritated.  People are irritating, sometimes situations are upsetting and at other times, things happen.  As recruiters, we might work contingent or on contract or for an industry player but either way, there are times when we've considered walking away either from an unreasonable client or from the field of recruiting all together.  "ENOUGH!" we said.  

Let's say you're working with a bad client.  Either they are irritating, rude, and demanding like a spoiled brat or they pay stupid low fees.  However, the reason you're working with them is that you fill positions.  You hate dealing with them but you get the job done and they pay.  Do you continue?

How about an employment situation?  You are working for a firm or have a partner who owes you money but you find out stuff about them that make your skin crawl and you want to bail.  It's the boiling point and you have to get out of there.  Do you leave the money behind or do you exercise patience even though you can't stand another minute of this nonsense?

What would you do?
