Two answers, in that order. National Boss's Day is October 16. When the 16th lands on a Saturday or Sunday, most offices observe it on the nearest working day, which is the Friday before or the Monday after. That is why the marked date appears to wander year to year. The calendar moves; the 16th does not.

Where Boss's Day even came from

The origin story is more charming than you'd expect. In 1958, Patricia Bays Haroski, a secretary at a State Farm Insurance office in Illinois, registered National Boss's Day with the US Chamber of Commerce. She picked October 16 because it was her father's birthday. He happened to be her boss. The point was to bridge the gap between management and staff and to give appreciation a date on the calendar. Four years later the governor of Illinois made it official. So the day was invented by an employee, for employees, to use on their own terms. Worth holding onto when it starts to feel like a tax.

Is Boss's Day mandatory? No.

Nobody is required to mark Boss's Day. A good manager will not be counting cards. It works as a bottom-up gesture or it doesn't work at all. If the team genuinely likes their manager, a card is a nice thing. If it's being organised out of office politics, everyone can feel it, including the boss. Small and sincere always beats elaborate and hollow. (Yes, I've been on the wrong side of that one too. The card I helped pass around for a manager nobody really liked in 2019 was the most cringeworthy hour of my year.)

What to write when you actually like your boss

Vague flattery is the trap. "Best boss ever, thanks for everything" reads like a printed verse. Point at one specific thing they did. The line I've used unironically four times, and would use again: name the moment, then stop.

  • "Thanks for the meeting last March where you took the blame in front of the client and never mentioned it again. I noticed."
  • "You made it normal to say 'I don't know' here. Rare. Freeing."
  • "You hired me when my CV was a gamble. I've been trying to make that a good decision ever since, and I'm grateful for the chance you took."
  • "Most managers manage the work. You also manage to keep Mondays bearable. Thank you, genuinely."
  • "Three words: best 1:1s ever."
  • "Thank you for the meeting you cancelled instead of running for the sake of it. That kind of restraint, applied for an entire year, has saved me roughly fifty hours and an unknowable amount of sanity."

Writing it from the whole team

A single card with fourteen cramped signatures says less than it should. When a team wants to thank a manager together, a card where each person adds their own line lands harder, because the boss gets to read what individuals actually think rather than scan a wall of initials. A group card multiple people can sign sidesteps the desk-to-desk pass-around entirely, which is the part I always hated about the analog version.

Keep any "from all of us" line short and let individual voices carry the rest.

  • "From the team: we know the stuff you shield us from. Thank you for absorbing it."
  • "A year of you having our backs. Consider this, briefly, us having yours."
  • "Thanks, Diane."

What to write if you don't love your boss

The honest part. Sometimes you're signing because the team is, and you don't have a warm specific memory to draw on. Don't fake one. False praise reads as false, and you have to keep working with this person on Monday. Stay professional, true, and brief. "Thank you for your leadership this year. Wishing you a good Boss's Day" is completely acceptable and commits you to nothing you don't mean. Sincerity is mostly about not lying. It is not about gushing.

Cards, gifts, and not overdoing it

Etiquette on gifts is refreshingly simple: modest, and group-based. An expensive individual gift to a manager can look like currying favour and puts colleagues who didn't pitch in an awkward spot. A shared card, optionally with a small group contribution toward a team lunch or something the whole team signs off on, keeps the gesture warm and the office politics out of it. If you do want to attach something, our note on group gifts that travel with the card covers doing it cleanly. Honestly though, the card is usually enough. The gift industry has a vested interest in convincing you otherwise.

Turn it into a group card and the bigger point

Boss's Day works best when it isn't the only time recognition happens. A card once a year for the manager, and nothing for anyone else, quietly says appreciation flows upward only. The healthiest teams send it sideways and downward too, which is the entire subject of our piece on employee recognition that actually works. If the Boss's Day card has you thinking about culture more broadly, read that next. It often does. You might also like our take on group cards and work culture, which is the longer version of why this matters.

When you're ready, create a card online and send the link before October 16 so people can sign in their own words on their own time.

One last thing, off-topic and probably just for me. The card my own team signed for Diane that year ended up on her bookshelf next to a framed photo of her dog, a basset hound named Walter who once ate an entire box of takeaway noodles off her desk while she was in a video call. She left that job two years later, and the card moved with her. I know this because she sent me a photo of it on a random Tuesday in 2023 with no caption. Make whatever you want of that.
