One of the best ways to build your volunteer team is to get them to do activities together and this also works well with paid staff. We broker lots of team challenges for groups of business employees, so why not think about doing a team building exercise with a difference for your volunteers? If you also have paid employees, you could involve them too and build employee-volunteer relations as a bonus.
A shared challenge and an opportunity to connect with other people in a good cause will give you all the feelgood factor and helps strengthen relationships within the team, so why not give it a try?
Many volunteers give their time because they want to help and what could be better than finding a fellow not-for-profit group who needs some help themselves? Your team could make a huge difference. It could be one-off challenge, such as doing some gardening or helping with an event, or something more regular.
