At my old job it wasn't the relationships you had to look out for, it was the hookups when everyone would go out drinking, whether the people were married or not. It used to make me sick when all of these married women/men would get drunk and use it as an excuse and then pretend like nothing happened the next day. I was single and had the chance to tag several married or extremely committed women just because their husbands either weren't around or were treating them like crap.
