Writing a birthday message for a work colleague

The British office birthday is a specific art form. Too effusive and it's odd. Too brief and it's dismissive. The sweet spot is warm and genuine, with just enough wit to show you actually thought about it. Here are 70 messages across every tone and relationship.

One card, every colleague

The paper card passed around the office means cramped handwriting in the margins and remote colleagues left out entirely. An online birthday group card from Thankeeu gives everyone full space for their message — plus photos from team events, GIFs, and an optional pooled birthday gift in GBP. Share one link, everyone signs from wherever they're working, and it arrives at midnight on the day. Create one here.
