That is an assumption, we don’t know the background on this agreement.
It may or may not be boiler plate stuff.
All you need to know is that the guy was let go in an "at will" state and provided with a five month severance package for only five years of employment.
That's a jackpot for anyone who has ever lost their job after so little seniority...........
I know exactly what the "agreement" says, I have issued them and I ultimately received one...........
Employment attorneys know exactly what that agreement says and the only way one will give it any consideration will be cash up front, probably in the neighborhood of $250. There's no way will he ever be able to find an attorney to take up his claim for a fee based outcome because there is now way he can win.
At this point I would advise him to file a discrimination claim with the state of Wisconsin and let them investigate it for free.
