Frequently Asked Questions
What should you write in a birthday card for a coworker?
Keep it warm but professional — a brief note about enjoying working with them lands better than something overly personal, unless you're genuinely close outside of work.
Is it appropriate to send your boss a birthday message?
Yes, a short, professional message is appropriate and expected in most workplaces — keep it brief, sincere, and avoid humor unless you already joke with them regularly.
What's a funny birthday message for a coworker who has a good sense of humor?
Office-appropriate humor about meetings, inboxes, or shared work frustrations tends to land safely — avoid anything that could read as a jab at their age or performance.
