Phil tells Gloria that if she works for him full time, he'll pay her $1,000 a week. As a result and based on Phil's promise, Gloria quits her job at the department store and puts a down payment on a car. When Gloria shows up at Phil's to start work, Phil tells her he's changed his mind about the full time job. What are Gloria's options

Gloria can assert promissory estoppel in order to enforce Phil's promise.

Explanation:

Promissory estoppel  refers to a legal doctrine that promises are legally enforceable. This doctrine establishes that in order for a promise to be considered legally enforceable, the party making the promise should reasonably realize that the other party will rely on it and that any reasonable person would rely on the other party's promise. This doctrine helps to avoid injustices by enforcing the promises.
