It's tiring to do ordinary work in the factory. Although the general worker's work is simple and has no technical content, the general worker works long hours and has no freedom. From work to work, he felt that there was endless work in the assembly and packaging workshop.
As long as it is a general worker, it is not easy to do it in any company. The dirtiest and most tiring job holds the position with the lowest salary and the least development prospect.
