Salaryman or Salariman (サラリーマン, sararīman?) is a Japanese term for a white-collar worker. The word is derived from English salary + man, and has since entered the English language in its own right. The Japanese term for the contrast term, blue-collar worker, is nikutai-rōdō-sha (肉体労働者). The word carries associations of long working hours, low prestige in the corporate hierarchy, absence of significant sources of income other than salary, wage slavery, and karōshi (過労死) or death from overwork.

White-collar workers perform tasks which are less “physically laborious” yet often more highly paid than blue-collar workers, who do manual work. They are salaried professionals (such as some doctors, airline pilots, IT professionals and lawyers), as well as employees in administrative or clerical positions. In some studies, managers are considered white-collar workers; in others they are not. The name derives from the traditional white shirts worn by workers of such professions. The white shirts are easily soiled and therefore distinguish the workers who “do not get their hands dirty.” (c) Wiki
