Supporting teachers is voluntary participation, so it does not violate paid vacation.

Paid vacation means that workers can enjoy paid annual leave for a certain period of time after working continuously for more than one year. China's labor law stipulates paid annual leave in principle, but it does not stipulate the vacation time and specific operation methods of paid annual leave, but designates the State Council to formulate corresponding specific measures. It is a common practice in labor systems all over the world to implement the system of paid annual leave for employees. The party and the state attach great importance to the construction of annual leave system in China. 199 1 June, the Central Committee and the State Council issued the Notice on Employees' Vacations, stipulating that party and government organs, people's organizations, enterprises and institutions at all levels can arrange employees' annual vacations on the premise of ensuring the completion of work and production tasks and not increasing the establishment and quota, and the number of days of employees' annual vacations varies according to the qualifications and positions of various personnel. The right to rest is a civil right stipulated in the Constitution of our country, and workers should enjoy it equally. In order to equally protect the rest and vacation rights of all kinds of employees and fully mobilize the enthusiasm of the broad masses of employees, the regulations cover all kinds of employers, and stipulate that employees of government agencies, organizations, enterprises, institutions, private non-enterprise units, individual industrial and commercial households with employees and other units can enjoy paid annual leave if they work continuously for more than 1 year. The unit shall ensure that employees enjoy annual leave. In the process of soliciting opinions, some localities, departments and netizens hope to increase the number of annual vacation days from 15 to 20 or 25 days at most. After repeated research, the relevant departments believe that the number of annual leave days should be compatible with the current level of China's economic and social development and the affordability of enterprises and other units. Therefore, the regulations stipulate that employees who have worked for more than 1 year but less than 10 year shall have an annual leave of 5 days; Annual leave 10 days if it is over/kloc-0 years but less than 20 years; Annual leave 15 days for those who have completed 20 years. At the same time, the regulations also stipulate that national statutory holidays and rest days are not included in the annual leave.
