Over the next six months the high-risk workers who were getting only medical treatment as usual missed fifty-six days of work due to sick leave, or about half of their assigned workdays. Statistics tell us that about half of these workers will leave the workplace permanently, go on full-time disability, and never work again. Those randomly assigned to receive the four hours of ACT training missed on average only a half a day of work over the entire six months—a 99 percent reduction in sick leave use.
