The RETURN Act directs the Secretary of Labor to help stroke survivors and people who have experienced other serious health conditions like traumatic brain injury or heart attack return to work. Working with the Department of Health and Human Services, the Labor Department would spread information and raise awareness among survivors, their families, employers, government agencies, and service providers about job return options, workplace accommodations, and self-employment opportunities. The bill also requires the Secretary of Labor to submit an annual report to Congress starting one year after the law takes effect describing the actions taken under this program. The legislation does not specify dedicated funding amounts or strict timelines beyond the annual reporting requirement, leaving implementation details to the Labor Department's discretion.
