in the L.A. area, both CVS and Safeway/Von's have got programmes where they hire adults with learning or behavioural disabilities and train them, in concert with job coaches.  once yer in, it's a job for life, too - they can't fire ya, excepting gross malfeasance.  e.g. I went into a CVS store and there was a woman squatting on the floor, making moaning noises and rocking back and forth.  when I pointed her out to the manager, he said she was an employee who was mentally challenged.  she's still there, 6 months later.  I thanked him for hiring handicapped individuals, especially in this economy.
