I know of a couple of cases and some broke up their families and
got married to each other. Others have blatant affairs and the
office will have stories to tell. Others sleep around till wife
call up another colleague to counter check and they broke up.
Anyways, it bad in all directions but it happens. Thrill or no
thrill, its not something you want to expose yourself due to many
reasons, such as how your colleagues see you, your promotional
aspects and how does this affect your family and life. The last
case, he regretted and even profess to love his wife (and yet hurt
her till this manner) but the wife refused to with him anymore and
wanted to cut ties and she gots lots of his $$$.
People are stupid and weak.
