Is it legal for nurses to support hospitals during the compulsory probation period?

Illegal. It is illegal for a hospital to support nurses during the compulsory probation period, but if it supports epidemic prevention in other provinces, the hospital can. Generally speaking, if the hospital can, the hospital leaders certainly hope that the medical staff will not go out. After all, the consequences are serious, and medical staff are not immune to all viruses, but sometimes there are government tasks and medical staff's responsibilities, and hospitals can only arrange the province to support nucleic acid testing. In an emergency, I hope everyone can understand each other.
