I hate seeing this down-voted. It is such an important warning to people here. Severance agreements are pretty strong. Also, be very careful of snap settlement offers.

So many of the greatest tragedies I've seen inflicted on people come from accepting an expedient way to get what is really a small amount of money quickly. So often the drive is paying the rent/mortgage or fear of losing health benefits. If you are in a bad situation and offered a settlement and you really feel like something isn't right please talk to an employment lawyer. Most US States have expedited processes for quickly resolving these cases, and the lawyer can help you a lot when you feel like your only choice is to take the severance.
