What's the difference between white-collar and blue-collar grades?

1, white-collar and blue-collar level difference: the nature of work is different: blue-collar refers to all working-class people who are mainly low-tech repetitive manual labor and low-tech office workers. White-collar workers refer to people with high academic qualifications and work experience. They are also called white-collar workers in western society who do not need to do a lot of physical labor.

2. Different classification: White-collar workers can be divided into traditional white-collar workers and new white-collar workers. After the reform and opening-up, the high-paid employees of foreign companies are the earliest white-collar workers in China, and now the traditional white-collar workers can basically be regarded as their continuation. Blue collar is divided into sharp blue, plain blue and dark blue. Generally, blue and dark blue are engaged in manual labor, while sharp blue is an intermediate transitional class, which may change to white-collar workers. Deep blue refers to people with certain skills.
