What is the treatment of dispatched staff in Tianjin Library?

Hello, I am a social worker in Tianjin Library. I just want to make a long story short Our socialized workers do the hardest and heaviest work, and the wages they get are not as much as the bonuses of regular workers. We have completed the preparatory work before the opening of the whole museum, but we can't guarantee a foothold in this society at all. We are not greedy and do not ask for equal pay for equal work. We just hope we can survive! Our current salary is only 1200, and the attendance award has been included. In other words, if you ask for leave, you can only get 1000, and you don't even have the right to get sick. I hope you can understand.
