Each year approximately 36 million days of work are lost because of declines in productivity related to mental illness. It is therefore critically important that the U.S. employer-supported health care system promote accurate diagnosis and effective treatment with a focus on return to work and that employers adopt policies that facilitate early return to work. To that end, the Partnership for Workplace Mental Health has developed a set of recommendations and tools for use by physicians and employers. The Partnership is a program of the American Psychiatric Foundation, with nearly 30 of the nation's top businesses, including Coca-Cola, 3M, Caterpillar, Dow Chemical, and Merrill Lynch.
