Shared English does not mean a shared holiday table. A “Thanksgiving week” invite can land in October for Canadians and November for Americans. A “May long weekend” means different Mondays in the UK and Canada.
This is an operations guide for calendar hygiene—not employment law advice.
Put three holiday layers on one view
In Google or Outlook, subscribe separately to US, GB, and CA holiday feeds (or the provinces you staff). Color-code them. When you propose an all-hands, scan all three layers before locking the date.
High-confusion pairs
U.S. vs Canadian Thanksgiving are different months. Boxing Day matters for many UK support queues while U.S. federal offices treat December 26 as a normal workday unless it is an observed Christmas holiday. Early May UK bank holidays do not map to U.S. Memorial Day.
If only one region is offline, record the meeting and rotate the “who stays late” burden across the year instead of always protecting the U.S. calendar.
Customer support and SLAs
Publish a simple coverage matrix: which holidays reduce chat/phone staffing in which region. Do not hide behind “we follow U.S. federal holidays” if half your agents are in Toronto or Manchester.
- Never synonymize the two Thanksgivings in meeting titles.
- Spell the country in the invite: “UK Early May bank holiday.”
- Revisit the matrix every January when new-year dates publish.
FAQ
Should we block the entire Thanksgiving week for U.S. staff?
Many teams reduce meetings Wednesday–Friday, but that is policy, not federal law. Be explicit in the handbook.
