Working Hours in an Email Signature

A working hours line is a short note in the signature about when the sender is available. It comes in two common forms. The first states the sender's own pattern, such as Working days: Monday to Wednesday, or Hours: 8:00 to 16:00 CET, which suits part-time staff and people in a different time zone from most of their contacts. The second form is about the recipient: I work flexible hours and sometimes send email outside the working day; please do not feel obliged to reply outside your own working hours. That version spread widely as remote and flexible work grew, and many employers encourage it as part of wellbeing policies, since it removes the implied pressure of a late-night email. A time zone label, such as Based in Singapore (GMT+8), helps distributed teams schedule without asking. The line should be short, in smaller text than the contact details, and placed after them. If working days change regularly, a scheduling link that shows real availability is more accurate than static text. Organizations that standardize signatures can offer the note as an optional line rather than forcing it on everyone, since it suits some roles better than others.
