I was given a non employee poaching contract to sign when I gave my notice at BIGCORP. It had some vague language like "I will not attempt to contact any BIGCORP employees with information about other positions". I gave it back to the manager at the exit interview unsigned and said nice try. I guess they are just hoping someone doesn't read it.
