If one day isn't enough time for you to celebrate, April 15-21 is known as National Volunteer Week or Volunteer Recognition Week and the entire month of April is Volunteer Recognition Month.
So, you better recognize!
Ideally you would recognize your volunteers year-round. I mean, they come and go so fast. Don't wait until April to say thanks.
Typical gifts for Volunteer recognition include cards, pins, letters, speeches, parties, gift certificates, lunch, and gift baskets.
