My girlfriend is an intern in a hotel now, but she often loses her temper in the hotel and asks for leave due to illness. She doesn't want to work in this hotel. ...

This is not a big problem. It's normal to get angry at work. Any position will exist. If you really don't want to do it, discuss with the school, and the school will agree, but you may lose something. For example, the school will no longer provide employment opportunities, and the school evaluation will be lower at the end of graduation. Because you don't follow the school curriculum, it is wrong for the school not to give you a diploma. Unless it is a overlord school, there is no way but to resort to law.

That's basically all. It's best to stick to the school arrangement. "Nine times out of ten, life is unhappy." You can't stop doing it because you're angry. You will encounter these problems in your future work, even when you become a boss. If you follow your ideas, you will do nothing and nothing in your life, right?

There is also the question of asking for leave. If you have a little cold and headache, you can stick to it. If you have a fever, you can't persist. They will also allow you to explain the situation to the person in charge of the school catering practice hotel. Be serious and responsible for your work, and you can't always take time off and escape with luck.

I hope what I said above is helpful to you, and I wish you all the best in your future work and life!
