Legal analysis: If an ordinary worker resigns, he only needs to notify the employer in writing one month in advance to terminate the labor relationship. If the employer forces the laborer to work by means of violence, threat or illegal restriction of personal freedom, or if the employer illegally directs or forces the risky operation to endanger the personal safety of the laborer, the laborer may immediately terminate the labor contract without notifying the employer in advance.
