What Exactly is a Stay Interview?
It’s the opposite of an exit interview, in which you try to determine the factors that led to a worker’s decision to leave your employ. Ideally this type of preemptive measure will cut down on the number of talented employees lost.
A stay interview, conducted periodically, is distinct from a performance review. Its basic goal is to determine why the employee continues to work for you, so that you can, within reason, keep those factors alive.
