The odds of a small enterprise surviving for 50 years are fewer than one in a hundred. Now imagine trying to survive half a century while relying on employees who are called upon regularly to risk their lives and who are not paid. That’s the story our roving reporter Rotbart has spent the past 18 months chronicling for his new book, Dedication and Service: 50 Years on Call with the Volunteers of Colorado’s Genesee Fire Rescue. It’s an organization with roots dating back to Benjamin Franklin and his “Bucket Brigade” of 1736. This week, Rotbart and his son, Maxwell, invite Jason Puffett and Hank O’Brien to explain what motivates their firefighting crew and what for-profit businesses can learn from the enduring success of their fire company.
