What is the strength of Dalian jinzhou area Heavy Machinery Co., Ltd.? How about the treatment of undergraduates and the basic salary and welfare?

I am a worker in a heavy machinery factory. Our workers have no welfare. They have worked there for five years. They were assigned there after graduation from technical school, but they didn't transfer. The labor contracts they signed were all fucking picked by the leaders. Whether the worker is alive or dead, overtime is free. The basic salary of undergraduates is around 2000/2800. As for welfare, can it be better than our workers? The most important thing is flaw detection. Do you know what this is? It is radioactive radiation, which is harmful to people's health and affects fertility.
