Your manager sends a message after you have clocked out. Do they need an answer tonight? Check the wording, your team’s emergency contact rules, and whether actual work is being requested. If it can wait, reply during your next shift. If you are asked to work now, confirm the priority and how to record the time.

What to do when a message arrives
- Check your schedule and the agreed contact route. Are you on an on-call rota, or is this a normal day off? Read the message for a real deadline and a requested action. A message sent late does not necessarily ask for an immediate response.
- If the deadline is unclear, ask briefly. 本件は明日の勤務開始後の対応でよろしいでしょうか。 (May I handle this after I start work tomorrow?) If your workplace has a separate emergency phone number, use the specified route for a genuine emergency.
- If you are asked to work now, clarify the task and time. 本日中の対応が必要でしたら、作業内容と勤怠の記録方法をご指示ください。 (If this needs to be done today, please tell me the task and how to record the time.) Note the actual start, finish, and work performed. Follow your workplace’s overtime approval and attendance correction procedures.
- If it can wait, respond in your next working period. ご連絡ありがとうございます。明日の始業後に確認してご返信します。 (Thank you for the message. I will check and reply after I start tomorrow.) For a shift worker, “tomorrow” may be a day off, so say 次回の勤務開始後 (after my next shift begins) instead.
Keep a record when you actually work
Japan’s Ministry of Health, Labour and Welfare (MHLW) says employers must appropriately ascertain and manage working time; its working-time record guideline explains the principle. Whether a particular call, message exchange, or standby period counts as working time depends on the actual circumstances, including the employer’s instructions. Do not assume that every notification is work, or that a short task is too small to record. Tell your manager or HR what happened and ask for the correct entry if the system has already marked you as off duty.
MHLW also notes that after-hours email instructions can contribute to long working hours, and describes employer measures such as limiting those messages and setting procedures for work outside normal hours in its telework guidance. The same practical question matters whether you are in an office, on a work-from-home day, or between shifts: what is expected, when, and how should the work be recorded?
Set expectations before the next message
Ask your manager which issues really require an immediate call, who is on duty, which channel to use, and when routine messages can wait. You can say: 勤務時間外の緊急連絡は、どの方法で受けることになっていますか。 (How are we supposed to receive emergency contact outside working hours?) If your schedule itself has changed, check the shift schedule rather than relying on a chat message alone. Company rules and individual work arrangements differ, so confirm your own procedure with your manager or HR.
