So, after getting the RIF, if you've been there less than 2 years, you will not be fully vested in the 401K program; if you've been there less than 3 years, you won't see the additional 4% so all that money you thought you were getting according to your Fidelity account is a complete joke.
Your account will show a "forfeiture" for the matched amount. I think some of this RIF mess is to avoid having to match folks' retirement contributions they tout so highly as a "benefit."
