We stopped giving awards about 10 years ago now. Think of it like a beauty pageant, you make one person really happy, but the rest not so much.
Everyone one smiles and offers congrats to the winner, and then start talking about it to each other...why did she win, I have more hours, I have served more years, she is the staff's pet, I hosted the fundraiser that was our biggest success and nothing. I worked my fingers to the bone wrapping presents at Christmas and all I get is sore fingers.
Also when was the last time someone younger than 45 was recognized? What message are you sending to your younger volunteers who also work full time?
