Sounds like the product of decades of overregulation from the government and overlitigation from the ambulance chasers (two groups with a lot of overlap not only with each other, but with liberal/democrat/moonbats as well)
Yep. If this story is true, the employee needed to provide documentation of their physical limitations so the employer could provide ADA compliant accommodations to keep from getting sued by the employee or fined by the Government, or both. It's pretty standard policy, especially outside of the white-collar world. Over the years I've had to put several employees on "light-duty" for some temporary medical condition and required a doctor's clearance before I returned them to their normal duties. I don't really think the requirement is a bad idea, if it's not abused. Used properly the employee is protected from potentially injuring themselves worse and the employer is protected from liability.
What I would like to know is, if Aristus is so very much against capitalism, did he bill the patient for services rendered? And, as been pointed out numerous times over the years, why does he keep trying to present himself as a doctor when he isn't?
