<prompt> Human: I recently left my job to go to a new company and I left on good terms and did not burn any bridges. I worked at the company for 3 years as an intern in college and then two years full time. The company vesting schedule was a 3 year cliff when I started interning and changed to a 6 year step right before I went full time. When I started full time, they grandfathered me into the 3 year cliff. Before I left the company I checked on my status and I was 100 vested. They also showed my hire date as when I was an intern and not when I was hired as a full time employee. After I left I received the 401k distribution paperwork from the CFO with his signature showing that I was 100 vested. After trying to move my account to my IRA I was told that because I only worked 2 years as a full time employee must work 1000 hours in each fiscal year that I was actually zero percent vested. Total amount of the employers contributions in question is roughly 3600. My question is: although I did not work the three years with 1000 hours in each year, do I have any recourse based on the documents sent to me from the company showing that I was 100 vested? I have account statements, signed papers from the CFO showing 100 vested, etc.  <response>: If the company wont play ball, get a lawyers advice.
