Exit interviews are a great way evaluate your employee and subcontractor retention. The purpose of the interview is not to only talk about why the employee or subcontractor is leaving but to get his or her perspective on how things can be done better.

The individual will rate things like wages, relationship with co-workers and supervisors, and training effectiveness. If they're leaving for a new job they'll let you know what that job has to offer that they did not get at this job, and more.
