A few months after starting a new job my employer required me to sign an agreement that I would forfeit my accrued PTO (paid time off) if I did not give 30 days' notice when resigning. I received nothing in exchange for my signature and the company policy for non-managerial employees is to pay out PTO on two-weeks' notice.
If I resigned on two weeks' notice, would my employer have a legal right to my PTO?
I suggest a local attorney consultation, bringing with you all the relevant documents--employee policy manuals and all employment agreements. It is most difficult to give a definitive answer without reviewing all pertinent documents and circumstances. Generally speaking, contracts do require some consideration. Good luck.
Generally speaking, contracts require some consideration. There may be instances where you can have a quasi-contract action called promissory estoppel if you rely on a promise to your detriment. With respect to whether the provisions of an employment agreement are binding on employers that will often depend on state law. For example, in Missouri they are not binding, but are in Nebraska.
