Mason who has a degree in business administration, interviewed for two positions, one as a credit manager for a large bank and the other as a financial planner. He received a phone call offering him the credit manager’s position, which he accepted. Two days later he was offered the financial planner’s job, his first choice. He also accepted this position and then called the bank to say he had changed his mind about taking the credit manager’s position. Has Mason breached a contract with the bank?
