This is one of three policy action papers prepared as part of the Stay-at-Work/Return-to-Work Policy Collaborative, an initiative funded by the Office of Disability Employment Policy in the U.S. Department of Labor. Each year, millions of workers in the United States lose their jobs or leave the workforce because of a medical condition. Keeping these workers in the labor force could help them stay productive, maintain their standard of living, and avoid dependency on government programs. In this paper, we present actionable policy recommendations for expanding evidence-based early intervention services to those workers who may be the most likely to return successfully to work if they get help early. Recommendations for both state and federal government are included.
