There are times when people cry at the office. We've had two indicents here recently - one person was really being harangued to no end by her great blimp of a boss, and just broke down. The other was a young mother just back to work after mat leave and was having some problems adjusting. I can't say I frown on either of these young women.
So, even though the way you make it sound is that this person is unjustified with her tears, I wasn't there and can't say. Who knows, maybe you're an evil boss?
