It is a violation or illegal act for a teacher to engage in a second occupation that has nothing to do with his work, and he will not be sentenced.

A second occupation that has nothing to do with work contains a lot of contents, and a second occupation that violates regulations or laws usually refers to a second occupation that aims at making profits. It directly or indirectly affects the professional image and work efficiency of public teachers. For example, paid tutoring is a second occupation explicitly prohibited by the state administrative and educational organs, which is incompatible with teachers' selflessness and answering questions.

For example, a second job, such as running a hotel or doing business, will seriously affect the quality and energy of teachers' teaching and education. Therefore, engaging in an unrelated second occupation is contrary to the teacher's image and work efficiency and is prohibited by the administration.

As for those who have been sentenced for engaging in a second occupation unrelated to teachers' work, it means that engaging in an unrelated second occupation has seriously violated professional legal norms. For example, in the catering profession, in order to increase profits, people who adulterate food or add toxic and harmful substances prohibited by the state, causing casualties or poisoning, may be sentenced according to relevant laws.
