About working for three days, not because of me. Is it reasonable to dismiss my property and not pay me? If it is unreasonable, how to protect rights?

As long as the employee has paid the labor, then the employee has the right to enjoy the labor remuneration, and the unit needs to pay the salary of the employee.

Generally speaking, employees need to negotiate with the unit and ask the unit to pay wages on time. If you have any objection, you can complain to the local labor inspection brigade for mediation. If mediation fails, employees can complain to the labor department or apply for labor arbitration claims. And can advocate the dissolution of labor relations and demand payment of wages and economic compensation.

According to the "Provisional Regulations on Wage Payment"

Article 9 If the labor contract is dissolved or terminated by both parties in labor relations according to law, the employing unit shall pay the employee's salary in one lump sum when dissolving or terminating the labor contract.

Eighteenth labor administrative departments at all levels have the right to supervise the payment of wages by employers. If an employing unit commits one of the following acts that infringe upon the legitimate rights and interests of workers, the labor administrative department shall order it to pay wages and economic compensation to the workers, and may order it to pay compensation:

(1) Deducting or delaying the wages of workers without reason;

(2) refusing to pay overtime wages to laborers;

(3) paying workers' wages below the local minimum wage standard.

The standards of economic compensation and compensation shall be implemented in accordance with the relevant provisions of the state.

Article 19 In case of a labor dispute between a laborer and an employer due to the payment of wages, the parties concerned may apply to a labor dispute arbitration institution for arbitration according to law. Anyone who refuses to accept the arbitration award may bring a lawsuit to the people's court.
