Frequently asked questions
- What do you write in a birthday card for a coworker?
- Wish them a happy birthday, add one specific thing you appreciate about working with them, and finish with a warm wish for their day or year. A short, friendly line is plenty. If you don't know them well, something simple like "Happy birthday, hope you have a great day!" is perfect.
- What is a funny but professional birthday message for a coworker?
- Keep the joke about work rather than the person: meetings, snacks, the office cake or their inbox are safe bets. Avoid jokes about age, appearance or anything personal, and only use inside jokes the whole team will get.
- Should I write something different from a manager or for a boss?
- Yes. From a manager, thank them for their work and tell them to enjoy a day away from the inbox. For a boss, a sincere thank you for their support works better than a joke. In both cases, keep it warm and short.
- How do I get the whole team to sign a coworker's birthday card?
- Use an online group card. Create a birthday card, share one link in your team chat or by email, and everyone adds a message, photo or GIF from any device, with no account needed to sign. Send it on the morning of their birthday, or schedule it with Premium.
