Alonzo graduates with a 3.8 GPA in Accounting from a New York university and receives offers of employment from three of the Big Four accounting firms. While considering his options, a mid-sized firm in California calls and offers him twice the starting salary of his top offer. The only caveat is he needs to show up at the Los Angeles office within the next week to start work immediately. Alonzo excitedly decides to take the California job. He refuses the other employment offers, breaks his lease in New York, sells or gives away most of his possessions, buys a new car, and heads for L.A. the next day. When he arrives at the Los Angeles office three days later, the firm apologizes and informs Alonzo that the position is no longer available due to the loss of a major client.

As per the theory of Promissory estoppel a promise made by an employer or entity to an individual/entity or any other subject even without any formal consideration cannot breach the promise on any basis including the any incident causing sudden crisis in organization.

The same happened with Alonzo and hence he can claim against his employer on the basis of Promissory estoppel theory.
