salaryman
An employee, a worker; now especially a Japanese white-collar worker who works long hours yet has an insignificant position within the corporate hierarchy.
In this way, the salaryman was both a progressive social stratum and an intellectual class.
Where it comes from
Phono-semantic matching of Japanese サラリーマン (sararīman), itself a wasei eigo (和製英語; pseudo-anglicism) derived from salary + man.
