ノー残デー

• 読み: ノーざんデー
• ローマ字: nō zan dē
• 漢字の分解: ノー (from English 'no') + 残 (from 残業, overtime) + デー (from English 'day') → no overtime day
• 発音: /noː zan deː/

意味

No-overtime day — a designated day when employees are expected to leave work on time without doing overtime.

ノー残デー is a corporate policy where companies designate specific days (often Wednesdays) when all employees are expected to leave at their regular end time. It's part of broader efforts to reduce overwork in Japan. However, the policy is frequently criticized as ineffective — many workers simply take their work home, come in earlier the next day, or skip ノー残デー when deadlines loom. The term captures both the genuine attempt at reform and the gap between policy and reality in Japanese work culture.

例文

1. 今日ノー残デーだから定時で帰れるよ。
