Let all birthday babies of a month blow the candles together and lighten up the workplace. This can be done in many ways. You can have a surprise party with a surprise funny gift on their desk and decorate their workstation with balloons and lanterns. Or if your’s is a big team or you have large number of birthday babies in a month let others in the team bring in sweets and cakes, share it with everyone and add some games if you want to make it more fun. Don’t take it easy when you paste them with creamy frosting.
