why quaternary workers are called as white collar workers
Dear Candidate,
Groups of working individuals are typically classified based on the colors of their collars worn at work. These can commonly reflect one's occupation or sometimes gender.
White - collar workers are named for the white - collared shirts that were fashionable among office workers in the early and mid-20th century.
A white - collar worker belongs to a class of employees known for earning higher average salaries doing highly skilled work, but not by performing manual labor at their jobs.
Hope it helps.
