Birthday Messages for a Coworker
Workplace birthday cards require a careful balance — friendly but professional, warm but appropriate. You want to acknowledge the day without oversharing or making things awkward.
These messages work for colleagues, team members, bosses, and anyone in your professional circle.

What NOT to Write to Coworkers
- Avoid age jokes — What's funny with friends can be HR-problematic at work
- Skip overly personal comments — Keep observations about appearance minimal
- Don't be sarcastic unless you're close — Tone doesn't always translate in writing
- Avoid inside jokes others won't get — Especially in group cards
- Keep it short — This isn't the place for lengthy prose
