If a bank employee is fired for cashing out his credit card, he can sue, but the chance of winning is very slim. Cashing out by credit card violates the state's management regulations on credit cards, infringes the financial management order, and violates the bank's internal management system. It is reasonable for bank employees to be fired for cashing out by credit card. If employees are dissatisfied, they can sue the bank. The bank can provide factual basis and system Basis and legal basis, but the employee has no factual and legal basis, and the court will rule in favor of the bank.
