Cross-Time-Zone Shift Work
24/7 factory, healthcare, and ops rosters — handoffs and UTC logging.
24/7 operations (plants, hospitals, data centers, SRE on-call) across countries need rosters that state **each shift's IANA zone** and UTC bounds. A common error: "early shift 6:00–14:00" without saying whether that is Chicago or Berlin.
Roster rules
- Each shift: UTC range + key city local time + IANA
- Handoff logs in UTC with local references
- Adjust US/EU shifts on DST weeks — avoid gaps or double coverage
- Combine with Global Call Center Time Zone Scheduling follow-the-sun where relevant
People considerations
- Stabilize night-shift teams in one zone when possible
- Limit surprise meetings to overlap windows (Remote Work Across Time Zones)
- Publish rosters 2–4 weeks ahead including Public Holidays and Time Zones
