First, I would have to read the entire separation agreement that you are writing about with respect to your soon to be former employer to comment upon its appropriateness and your ability to bring an age discrimination lawsuit or not if you signed it. As such, it is best to have a labor attorney review it in detail before signing it.With that being said, based upon what you have written, it appears that you would not be required at all to sign the separation agreement under the laws of most states in this country. Most times the employer simply has the employee sign a document stating what payment he or she is getting in the end as well as knowledge that certain benefits would be ending upon the end of the employment.
