The University of Miami has spent $40 million to build and maintain two on-campus wellness centers and offer programs to get its employees fit and healthy. It even has offered financial incentives to encourage participation from those less enthusiastic than Auguste, such as $150 medical premium credit for participating in an online health assessment and a 20% rebate on their wellness center membership. But like many other employers, the university still is grappling with whether its investment in wellness pays off and how far to go in coaxing employees to participate.
