Yes, employees of state-owned enterprises may be fired for overdue debts, especially for overdue credit cards. According to the Labor Law of People's Republic of China (PRC), if an employee violates the labor contract or national laws and regulations and causes losses to the enterprise, the labor contract may be dissolved according to law. In addition, if the arrears are seriously overdue, the bank may bring a lawsuit to the court to recover the arrears, which will also have a negative impact on the employee's credit history.

To sum up, employees of state-owned enterprises may be fired after the deadline, which depends on the amount of arrears, overdue time, enterprise regulations and other factors. Therefore, it is suggested that employees should pay attention to abide by the credit regulations in their daily lives and repay on time to avoid losses to enterprises.
