At present, the state has repeatedly banned in-service teachers from making up classes with pay. If what you said happens now, then the teacher has violated the relevant regulations of the education department. In accordance with the relevant regulations, in-service teachers are prohibited from participating in paid extracurricular tutoring classes and participating in extracurricular training institutions, and teachers are prohibited from providing publicity and other services for extracurricular tutoring institutions directly or in disguise. Scenario 1 has violated this provision, but it has nothing to do with professional ethics. In the second game, Mr. Liu made it clear that the students in his class had to attend the remedial class he presided over, which violated the students' original intention. Violating the principle of voluntary participation, Mr. Liu graded students who did not participate in counseling according to his own standards, which was illegal and violated teachers' professional ethics. For teachers who violate teachers' professional ethics, they usually have informed criticism or withhold part of their salary or cancel the promotion of professional titles and the qualification of evaluating the first tree.
