My friend is dealing with a similar situation, except he's the one that can't keep the job. In the two years that I've known him he's easily had 8 jobs, in part because he is a convicted felon (he got in trouble at the age of 17, 11 years ago, for which he served 7 years). I personally think that it's more than his record, but the record doesn't help either. He has like 3 degrees and he's a hardworker but...he has trouble with authority and refuses to work for less than a certain amount of money. I don't know how she does it but it's a HUGE strain on their marriage. But arguably, she knew what she was getting herself into.
