Send a message to other employees on behalf of the leader on birthday. How should I write my signature?

Leaders should not be too respectful to their subordinates, otherwise it will be disrespectful and will also make employees feel distant. Just use the words: Best wishes ... Happy birthday. To tell the truth, it is best to sign the name of the leader directly, which is both intimate and dignified. Don't use words like to or respect, and don't add leaders or positions.
