noun
Refers to a person who deliberately disrupts work or operations, often in an industrial or labor context. The term is relatively rare and may be encountered in historical or specialized texts.
工場で妨業員が機械を壊した。
A saboteur damaged the machinery at the factory.
Compound of 妨 (ぼう, 'obstruct') + 業 (ぎょう, 'work, business') + 員 (いん, 'member, person'). The exact historical origin is uncertain, but it likely emerged in early 20th-century labor or industrial contexts.
