I'm going to Change my last name. I've been married to my husband coming on 3 years. Poor kitty does not know which name to take. Mine or my husbands. So now as my husband puts it... "we will be a family". I would like to hyphenate it, but I'm not sure if they do that still.

My boss has not changed.
Okay... I have vented. It's only day one of our new project... a multimillion dollare endeavor(which includes the bills)

Can I change a co worker.... for a new one?
