The term “blue collar” was first coined in the early 20th century when workers wore durable fabrics such as blue jeans or chambres. The dark color would help mask the dirt and grease that was part of their job.
These non-office workers engage in physically demanding tasks, work outdoors in inclement weather, operate heavy machinery, and rely on their hands and strength.
Their jobs are usually in the trades, such as electricians, welders, carpenters, plumbers, builders, landscapers, farmers, miners, and manufacturing, factory, construction, and maintenance workers.
While many workers make a nice living and aren’t buried in tuition, they are considered the “working class” and are compensated by the hour or assignment, unlike office workers who are paid salaries and bonuses. A large number of this cohort had to train, apprentice or go to school to learn their trades and are unionized to provide relative job security, good wages and benefits.
The top jobs tend to be skill occupations that require technical skills and training, but not necessarily a four-year degree, and have strong six-figure earning potential. Workers for these jobs are in high demand and have future growth opportunities.
