Why have major supermarkets on the Internet been recruiting cashiers and financial assistants? Is it true?/You don't say.

There are two possibilities, one is because the cashier or financial assistant positions in supermarkets are in great demand or frequently flow, and the other is that the recruitment in 58 cities is free to publish information. However, some services are charged, and the charging period is not by day or time, usually several months or even a year. Therefore, from the point of view of the merchants who publish the recruitment information, the money has been spent anyway, and refreshing the recruitment information several times can be regarded as a publicity for the enterprise.
