Flirting with women in the workplace is flirting with big trouble. Make friends with the guys and keep it professional with the unprofessional gals.
I remember seeing an attractive girl who would go and talk to this poor guy about Howard Stern and all kinds of sex jokes. One day, he comes up to her and brings up a Howard Stern subject and she decides that she was offended and went straight to HR. Next day he was escorted out although he was a great guy and a hard working productive employee.
With that said, marriage is a good thing for a man. Working with women in the workplace is a bad thing for men.
