Can contract workers pay or stop paying medical insurance during sick leave in institutions?

According to the relevant information, no employer pays medical insurance for employees on the premise of labor relations between the two parties. As long as there is a labor relationship between the two parties, the employer must pay medical insurance for employees according to regulations. As employees of the company, they are still employees of the company during sick leave, and there is still a labor relationship with the company. Institutions need to continue to pay medical insurance. Therefore, contract workers are not allowed to pay or stop paying medical insurance during sick leave in institutions.
