You’re an excellent companion to work with and I wish you an extra special day. Happy birthday to a great coworker. Here’s to having the best birthday!

Happy to the Employee of the Month (in my books, at least). With a coworker like you, I don’t think I’ll ever have to look for another job. You make work more rewarding and, more than anything else, super fun.

You do not always have such good co-workers, so I feel very fortunate to labor with you. Thanks for all the things you taught me, and on the day of your birthday I want to tell you to have a very happy birthday.

Every day, time just flies at work. That’s because of you. You strike the perfect balance between professionalism and fun! Happy birthday to my favorite coworker.

In the corporate world where competition is cut-throat, helpful and supportive colleagues like you are more important than college degrees. Happy birthday to my man Friday.

You deserve a wonderful birthday. Hope it’s fun!

Happy Birthday to one of the reasons it’s great to work here!

You make this place tolerable — and that’s not easy! Happy Birthday! (Let’s grab lunch/drinks soon!)

Happy Birthday to the world’s best coworker. Feel free to send a similar message to me on October 11th when it’s my birthday!

You’re a real professional and a great friend, too. You deserve to be happy on your special day. Happy birthday and hope all your wishes come true.

The real meaning of teamwork is not in management textbooks but in the teachings of mentors and colleagues like you. Happy birthday and thanks for being my teacher.
