Some become prima donnas and will leave if they don't always get their way. Thankfully, they are in the minority. Some employees today have little corporate loyalty, so leaving is not as traumatic as it was 10 years ago.

It must be accepted and analyzed, and an ongoing plan must be established to manage it.
