Why do sorters recruit people every day?

Because this job is in great demand and there is a large turnover of people.

Sorter, as its name implies, is the work of placing express or logistics products by region, and the demand is large. Most express sorters just earn some quick money temporarily or work part-time at night, and many people don't want to do it for a few days, so the turnover of personnel is large.

The finishing work has been basically finished. At first, I was full of energy, and I finished my work quickly. When I get off work, my speed is much slower, and the sorter often sweats.
