Help make it the former with inspiration from the many great ways to say “happy anniversary”.

Giving a direct report a shout out on their work anniversary is a must.

Highlighting the way they show frequent appreciation also makes it more likely fellow employees will take note and follow suit, contributing to a culture of recognition .
11. Appreciating great feedback on an anniversary
I can’t say enough about how valuable your feedback this year has been, Claire. Your insights have helped us reshape our processes and culture for the better. Please keep exercising your voice, and happy anniversary!

Remember, though, that private or anonymous feedback must stay confidential, so only send this type of message to team members who have provided input publicly.
