Put in your rotation and see who holds Thanksgiving, Christmas and New Year's Day before anyone buys plane tickets.
@sarah gets Thanksgiving and Christmas. Swap one of those shifts with @sam, who has no holiday yet, and tell them now instead of in December.
A weekly rotation looks fair because everyone gets the same number of weeks. But the Thanksgiving shift and the Christmas shift are usually exactly four weeks apart. In a rotation of four, four weeks later is the same person again.
It doesn't happen every year. When Christmas lands on a Monday, like it does in 2028, a Monday handoff puts it five weeks after the Thanksgiving shift instead. A different handoff day or team size moves it too, which is why it's worth checking yours.
I'd look now, while a swap is still easy to ask for. Trade one of the two shifts with someone who has no holiday, then tell the whole team who has what. The swap only helps if people can see it, so put it somewhere they already look.
Tellspin keeps your on-call rotation in Slack. A swap is an override on the schedule, and an @mention reaches whoever is on call that day. Try Tellspin free in Slack

Who gets the holidays on your team?
I built Tellspin so on-call in Slack is easy to run and fair to share.
