If you have signed an internship contract, there are generally the above-mentioned terms of resignation, and you just have to do it. If there is really a clause that you can't leave your job and resign, then I'm sorry, there is no way out. I'm not sure if this is the overlord clause. You can consider consulting school teachers and relevant legal personnel, which will be very troublesome and may involve judicial proceedings.
(2) If the internship contract is not signed or signed but there is no resignation clause in the contract, then the operation at this time is very flexible. Basically, you can consider sending an email to your immediate supervisor or calling him directly (here, you should think of excuses or reasons for leaving your job, such as going to graduate school, going home, getting sick, etc.). ), he will tell you exactly what to do. You need to continue to negotiate with the company here.
If the negotiation is successful, it is possible to agree on a time to complete the handover and then leave. Of course, it doesn't rule out that some companies have some procedural troubles, and you need to go to the relevant personnel of the company's human resources department to go through the resignation procedures. If you have unpaid wages, you may be found by a financial officer.
(3) If the negotiation fails and you really want to quit, then I suggest that you consult the school teachers and relevant legal personnel, or even resign and take legal action with the enterprise (see if you have any legal advantages).
If it doesn't work, it may not be possible to quit, or it may be forced to quit, and bear the liability for breach of contract as stipulated in the contract.
Finally, I wish you all the best.
