At first, the hotel said it would take four days off a month, and a few months later, it said it would take two days off. Is it illegal?

This practice of the company violates the labor law. If employees have the right to take a vacation, the company can't deprive them of it. The labor law stipulates that they should work 8 hours a day and no more than 44 hours a week. Overtime wages are paid according to the labor law. If the employer still fails to perform the labor contract, the employee may apply to the labor arbitration committee for arbitration and take a vacation according to the vacation time agreed in the labor contract.

Due to the needs of production and operation, the employer may extend the working hours after consultation with the trade unions and workers, and generally the working hours shall not exceed 1 hour per day. If it is necessary to extend the working hours for special reasons, the working hours shall not exceed 3 hours per day, but not more than 36 hours per month under the condition of ensuring the health of the workers. If there are no other legal circumstances, and the company is suspected of violating the law by arbitrarily extending working hours, the employee may request to terminate the labor contract with the employer and ask the employer to give certain economic compensation.
