You are great to work with; everybody in the company loves you because you are an awesome person and a trusty friend. I am thrilled to work alongside you and to share this special day with you.
I hope you have a fantastic day and a fantastic year to come!
I hear that congratulations are in order for you today, my dear work buddy! Happy birthday!
When better to tell you than on your special day how much of a privilege it is to work with someone as wonderful as you! You're an inspiration my friend, truly!
Another year and your will to do more and achieve more just keeps increasing. Always with your eyes on the prize, you just keep going until you get there.
I wish you the best of birthdays because you deserve it, ma’am!
