Some of these might surprise you!
Reason #10 - The reality of their experience is not what they expected when they signed on.
Reason #9 - They don’t like the work they are being asked to do nor how it is being done.
Reason #8 - Veteran or leadership volunteers won’t let them into the “insider” group.
Reason #7 - They spend more time meeting than doing.
Reason #6 - No one listens to their suggestions.
Reason #5 - They feel unrecognized, and see that thanks are unfairly given to everyone, no matter who did the most work or none at all.
Reason #4 - They are no longer asked to participate.
Reason #3 - They do not actually understand how to get more involved.
Reason #2 - They can no longer see how their involvement makes a difference.
And the #1 Reason volunteers leave is........... - It stopped being fun. This doesn't mean every meetup needs to be a party, however for a volunteer to stay it has to be an experience they enjoy. Remember that a volunteer is there by choice and if they aren't finding personal value in the experience they are likely to put on their walking shoes and look for something more rewarding.
