The junior school was assigned to a hotel for five months, and chose to continue to do formal work after the internship. I'm at the switchboard because I don't like being late.

It seems that you are still a big boy who is about to enter the society, and you know nothing! Simple as white paper! Alas ..... I am an adult to answer your simple question! According to China's labor law, labor contract law and relevant judicial interpretation laws, it has not signed a formal labor contract with the relevant employer and is in the probation period (internship period); If you don't want to work, you don't have to write a written resignation to your employer one month in advance. The reason is very simple, because people have not officially hired you, so there is no job-hopping job. Say hello at most, don't wait until tomorrow, you can leave at any time. You can't deduct wages and certificates, but you can also file a lawsuit in labor arbitration. A complaint is accurate, but unacceptable, ok!
