Blue-collar worker

The term "blue-collar" refers to workers whose jobs are based on manual labor or technical skill, typically carried out in factories, construction sites, farms, fishing, mining, transport, and service industries. It contrasts with "white-collar" work, which encompasses office and administrative roles.

The name derives from the blue work clothing that such workers traditionally wore, which did not readily show dirt. Pay is typically calculated by the hour or by output, whereas office workers commonly receive annual salaries.

Types of work and skills

This category includes highly skilled workers such as welders, electricians, plumbers, carpenters, and mechanics, as well as workers performing routine manual tasks. Training typically comes through technical schools and apprenticeship programs rather than universities.

Worker organizations

Historically, this sector has been central to trade unions. These organizations have advocated for wages, working hours, and workplace safety. For much of the twentieth century, leftist and socialist movements drew significant support from industrial workforces.

Economic shifts

Since the late twentieth century, economically developed countries have seen declining numbers of blue-collar workers due to automation (machines replacing workers), robotics, and the relocation of factories to lower-wage countries. This has affected income and job security in many cities dependent on manufacturing.
