We have around 200 employees, and celebrate birthdays 1x/month at the end of the month. We have it at a recurring time (1pm, 4th Wednesday of the month), so people can plan and look forward to it. Funny spin is that we actually sing happy birthday, and sing off the names of all the folks we are celebrating. When we sang this month, there were 20 names we sung in a row together. It’s a bit silly and ridiculous singing all the names, but when I asked if folks wanted to stop, there was a resounding “no.” We’re a quirky group, so singing everyone’s names in a train wreck happy birthday song is very much part of our culture. Sadly, we will probably need to stop this as we grow. Teams have slowly begun celebrating amongst themselves, and we use Pingboard to display birthdays and anniversaries on a TV near our cafe.
