Matilda’s boss gives her an excellent employee evaluation and promises her that she’ll get a raise the next quarter. Matilda is thrilled by the prospect of more money because she desperately wants to enroll her daughter in private school. She enrolls her daughter in the private academy and a week later her boss advises her that, because of budgetary setbacks, he cannot give her the raise as promised, and in fact, has to reduce her salary. Matilda wants to try to enforce her boss’s promise. Which legal theory should she apply?
Unjust enrichment
Quasi contract
A breach of contract action
Promissory estoppel
