Explanation: According to the Labor Law of People's Republic of China (PRC), the labor contract between the boss and the employee is an equal contractual relationship, and both parties should abide by the contents of the contract. If the boss refuses to pay the employee's salary, the employee has the right to complain to the labor inspection department or apply for solving the labor dispute through legal channels. Even if the boss is sentenced to prison for a crime, he is still obliged to fulfill the labor contract signed with the employee and pay the employee's salary. If the boss refuses to perform the obligations stipulated by law, employees can apply for compulsory execution according to legal procedures.

Solution: If the boss is sentenced to prison, employees can file a lawsuit through lawyers or legal aid agencies, asking the boss to pay the unpaid wages. If the boss has been sentenced, but his salary has not been paid, the employee can appeal to the labor arbitration department and ask for compulsory enforcement of the labor arbitration award. If the boss still fails to perform his obligations, the employee can apply to the court for compulsory execution, which will be enforced by the court.

Extended explanation: the above solutions are for reference only, and the specific operation needs to be determined in combination with specific circumstances, such as whether the boss's company is bankrupt. If the boss's company has gone bankrupt, employees can protect their legitimate rights and interests as much as possible by applying to the bankruptcy administrator of the enterprise. In short, employees should maintain their legitimate rights and interests at any time and place, and should not be infringed by the boss's criminal behavior.
