Potential Employer asking for my last year W-2
I interviewed for a support position with a county school board in FL. Interview went great and they called all my references and seems like I'm the one they want. Now HR called me and wants a copy of my w-2? I've never heard of anyone requesting this when hiring new employees. The salary range was posted in the job advertisement. The range is more than I make now and they did ask for current salary before I interviewed. I've never heard of this business practice of asking for a w-2? Why would they need this?
