Is it illegal for the company to compensate for changing several companies for company reasons?

Your idea is meaningless.

I have been doing the same business in jinghuachang company for ten years.

It has nothing to do with changes in labor relations.

You go to arbitration

2n compensation will not be supported.

The reason is that there are a group of people in ten years, and the working system is jinghuachang's first company named.
