I worked as an intern in the company for a month, but I don't want to do it. How to tell the leader?

If you are looking for an internship yourself, you can leave directly, then send a text message on WeChat QQ and sincerely make up a reason to inform the leader. If it is introduced by your relatives and friends, if it is a non-interest relationship and a good friendship, then don't bother, explain it clearly and leave; In case you are introduced by someone who is not far away or stingy, you should handle it well. It will take a month to get rid of it, and you may accidentally offend others. Good luck!
