My file has been detained in the Education Bureau for more than two years. I had to live for five years when I signed the contract. I worked for two years, and the teacher resigned, but they didn't give me the file. In terms of legal rights, they have no such rights and are suspected of infringement.

But in real life, employers often use this way to block a person's personnel relations and files. Knowing that you have gone too far, in fact, the other party has several reasons to deal with you, so the chance of winning is not great. The only good way is to find an organ that can control it, correct it and let them file it.
