re: Sleeping with co-workers ok?

1. no, its not ok.

2. lots of people do it. You are playing with fire.
Look at the possible outcomes.
she loves you and you don't even like her. She haunts you all the time and you are embarrassed publicly from time to time and eventually she sues your parents and wins.
You love her and she doesn't. She sues you for harassment, by and by.
You love each other and you get married. You are sued by another co-worker for giving her special privilege or promotion the lawsuit says was due another person.
There are 5 or 10 bad outcomes and just a couple of good ones and the bad ones are REALLY BAD.
Try Craigslist.
