Shift assistants plus credits only have one letter of appointment, no salary and no other benefits. I really advise you not to help on duty, because you are really angry. At first, freshmen were out of control and had to teach. Counselors are dissatisfied with freshmen, and then they are caught between counselors and freshmen. It's hard to do things. At first, I thought the competition between the classes was fierce. As a result, when I became a teacher, I found that few people went to the class for help. Everyone thinks that class help is a very bad thing, which wastes their extracurricular time and is sandwiched between counselors and freshmen. Moreover, many freshmen don't understand the role of counselors and always resist. There are not many credits for helping on duty, just because of the letter of appointment. If there is no letter of appointment, even credits will not be added.
