Here is a note to congratulate your wife for her job anniversary. Job is tough to maintain when it comes to the prime lady in the family. Congratulate her on being successful in balancing the family and profession perfectly.
Dear [name of wife],
It is the day for you to celebrate as you have completed  years with the [organization name]. I do not know how you manage everything, your personal & professional life so easily. Every day, you seem never to get tired, deliver your excellent work that I really want to appreciate. I am pretty sure that all your co-workers want to tell you that we are thankful, for all your words of wisdom, all your kindness, and everything you have done to make your workspace pleasant in so many ways. A lot of people have tried and failed and what you have done and accomplished everything in these years. Reason is that other people are always trying to find problems but you are always trying to find the solution.
Every day, you still amaze me through your dedication to your work even after  years has passed by. You make not just me, but our whole family complete every single day. You showered me with unconditional love and were there for me through all my ups and downs. You are a woman stronger than anyone I know. Thank you for everything you did for me. You are an angel sent from above.
I hope that on your special day you are showered with all the appreciation you so richly deserve. Thank you for everything and happy anniversary to you and your work!
