What does blue collar and white collar mean

The term "blue collar" originates from the fact that workers wear blue overalls, which represent manual laborers who are mainly engaged in production, manufacturing and technology. They usually need to operate in factories, warehouses and other production places, which requires more physical strength and sweat. The blue-collar group has strong mechanical skills and operation ability in their work, which is an indispensable part of the manufacturing industry.

The term "white-collar" stands for knowledge workers, who are usually required to have a high educational background and professional skills, and are mainly engaged in administration, management, service and other fields. Compared with blue-collar workers, white-collar workers are usually more mentally oriented, require good communication skills and judgment, and are more often found in offices and business places.

With the acceleration of globalization, many traditional blue-collar jobs have been replaced by automation and mechanization. And emerging technology industries and harsh labor conditions have brought more and more white-collar workers into the fold. This trend is caused by the development of the economy and the times. Different career fields have their own skills and focuses, and we should choose a career that suits us according to our own interests and abilities to create a better future.
