White-collar workers are a definition of lifestyle in the west, which is usually used to represent professionals with higher incomes. This word may have been used from 1928 at the earliest. At that time, it represented non-manual workers, such as civil servants and faculty, and was a group in contrast with blue-collar workers.
White-collar workers are less engaged in manual labor, and the professional class in the company is often administrative or formal staff, who have professional working ability, such as doctors or lawyers. In some sociological studies, managers are sometimes classified as one of the white-collar workers.
The term "white-collar" first appeared in the early 1920s, and its scope included all non-manual workers who were employed and paid, so it was called "white-collar". Generally, their working conditions are neat, neatly dressed and their collars are white.
Including technicians, managers, clerks, salesmen, typists, stenographers, clerks, accountants, shop assistants, teachers, doctors, lawyers, ordinary staff and so on. These people have good economic income and working conditions, but because they have no means of production, they are still in employment.
In developed capitalist countries, the total number of white-collar workers exceeds that of blue-collar workers, accounting for about 60%-70% of the total number of workers. The white-collar class is an enviable class with good welfare, high income and stable status.
