If you are full-time, it is basically not Monday to Friday or weekends, but generally all day. Of course, you can talk to the employer about the rest time. Generally speaking, training institutions generally work for six days, and teachers decide the rest time according to the class situation, and there are also normal weekends. The stability and instability of their work depends on the enrollment of that training institution. If the enrollment is poor, they can't start classes, and the teacher will be laid off. At the age of 40, they mainly want to find a stable job.
