What should I do and protect my rights? Tell the Truth (True): Is Ningyang Store in Xixia District, Yinchuan City, Ningxia Treating Supermarket Promoters Improperly?

I personally think you should report the situation to your superiors. First of all, as a promoter, although the supermarket is not directly responsible for you, you are still a supermarket employee. You cannot say that you should or should not do some things. No additional ones are implemented, you are all the same relative to other employees. Also, if these things are, as you say, undignified, personal attacks, and wrong, you should refuse and explain your reasons. If it can't be resolved, I think you should consider changing jobs.
