My boss found out because I have a co-worker with super sonic hearing... seriously. She overheard me giving the co-worker with new baby on the way hubby's info, she told boss about the conversation. The reason she asked about it is because it's common knowledge that I really don't care for this co-worker. He's a good worker, don't get me wrong, but his personality drives me up a wall, so we weren't exchanging info for social reasons.

The big deal, in my boss's point of view is that I am stealing her work force. She sees it as a "stab in the back".
