The best workplace humour is inclusive: everyone recognises the jokes about Monday meetings or the fridge, and nobody is the butt of them.
How to write it
- Joke about work, not about age or appearance.
- Keep it short — the punchline should land in one line.
- Add their name so it feels written for them.
