they CAN just pay the employee out... however, not sure if that type of behaviour is called for in this situation.

personally, i would ONLY do that if i thought my children's well-being was in jeopardy. i don't think that would be the case due to my relocation. i would say that most helpers are reasonable people, just as most employers are reasonable. if you are being relocated, i don't think that a helper would hold that against you.
