Promissory Estoppel

Promissory estoppel works where one party has made certain representations and as such, the party making the representations is estopped from taking advantage of it when the other party acts in accordance with those representations.   Myself along with co-counsel are testing the waters in federal court on an employment case with this issue where a business does not act in accordance with their handbook policies.  I think this doctrine has some potential applications in other areas of law and will expand in the next few years.
