15. Volunteer for Charity as a Group
Fifteenth on our list of company team building activities: indoor and event ideas, is an altruistic one — volunteering for a charity as a group. What type of charity you pick, whether is building homes for homeless, or working in community kitchens, it doesn’t matter, all it matters that your team works together to help those in need. This noble activity is going to really bring them close together, and it is definitely one of our favorites.
