The Palm Beach Post recently wrote an article on Social Security's Ticket to Work program, which is a free program available to those receiving SSI or SSDI. 

The goal of the program is to offer vocational rehabilitation, training, job referrals and other employment support services free of charge as a way of assisting survivors in entering (or re-entering) employment.  By providing these services, beneficiaries begin working again while keeping hanging on to their coverage, thus increasing their financial independence and reducing reliance on their benefits as they transition back to work.

The article profiled Terry, who was downsized after a cancer diagnosis and started receiving Social Security disability benefits as she took an extended leave from working.  Through her benefits she learned about "one-stop career centers" - center set up across the country providing free employment-related support services.  Here, she coordinated her career preparation and job hunt by updating her computer skills, taking workshops on interview skills, and refurbishing her resume. Terry was then able to keep her Medicare coverage and cash benefits while gaining work experience during a Trial Work Period.
