noun
mediator; conciliator
A person who acts as an intermediary to help parties reach an agreement, often in labor disputes, commercial negotiations, or legal contexts.
労働争議の解決のため、あっせん員が派遣された。
A mediator was dispatched to resolve the labor dispute.
あっせん員の仲介で、両社は合意に達した。
Through the conciliator's mediation, the two companies reached an agreement.
仲介人 is a more general term for an intermediary or go-between, while 斡旋員 often implies a more formal or official role in mediation, especially in labor or commercial disputes.
調停人 is a mediator in a legal or formal dispute resolution process, similar to 斡旋員 but often with a stronger connotation of arbitration.
Compound of 斡旋 (あっせん, 'mediation') + 員 (いん, 'member/person'). The kanji 斡 is relatively rare and not in the jōyō list, so the mixed kana form あっせん員 is common.
