How are pump truck operators treated?

About 4,000, more skilled ones

But there is definitely no prospect for development

There is a serious shortage of front-line operators, especially in engineering units, who have basic skills I won’t let him go

Go and take a look at the current construction site. There are several front-line workers who are twenty years old, and they are all about forty years old

This is how society is , it is more discriminatory and unfair to front-line workers, their status is not very high, and it is easier for people to look down on them if they develop upwards
