I went to Datang's electric power maintenance company for an interview and said it was a labor dispatch system. What's the difference between this and regular employees? What should I pay attention to? Labor dispatch is to repair the company through a third-party human resources company (which can be understood as an intermediary company). It seems that everyone works in Datang, but your actual unit is a third-party human resources company, which has nothing to do with Datang. In the future, if you are laid off, disabled or killed at work, Datang will push you far away. There is a simple reason. You are only sent to work by a third party, not a regular employee of Datang, and there are no benefits and promotion opportunities for regular employees. You'd better not go, because going in is just an exploitative life.
