Why does Shenyang subway recruit a large number of people?

The reason why Shenyang subway recruits more people is that there are few subway station attendants. The station attendants of Shenyang subway are all in shift system. When scheduling is needed, there are not enough station attendants. Every time a line is opened, there will be a corresponding station. These TV stations need to recruit new employees. The old employees have adapted to the work at the previous station, and now the subway or related companies will continue to recruit people to carry out related work. Subway station attendants need to rest more at their posts. Not many employees have to work more than 12 hours a day, but they all work in shifts. Once shifts are needed, employees will increase according to the corresponding situation. In order to make the site unusable, relevant companies will temporarily recruit, and relevant companies will recruit some temporary workers or labor dispatch employees.
