Today at work our squadron gave us a card with a gift card inside. There are like 20 people who signed it. What would be the proper way to thank them? Do I give each person who signed a thank you card? Do I send out a mass email? Or do I do nothing at all and just verbally thank people when I see them? It is weird because most thank you cards are more specific, like thank you for the card and money, but I dont even know who gave money towards the gift card.
