Brett, a sales representative at a store selling sports equipment, received an offer to join a competitor that promised to pay him 7.5 percent commission. When informed about this offer, his current employer verbally promised to pay Brett 10 percent commission "for the remainder of his life" subject to discharge only for dishonesty or disability. Brett accepted his current employer's offer and continued to work with the same company.
Three years later when Brett was fired, he sued his company for breach of contract.
