I recently saw a job ad for a JavaScript specialist where the position entailed having screenshots and keyboard + mouse tracking to monitor your working hours. It was a freelancer position, so the hire would handle taxes and health insurance, no equipment would be provided and working hours would start at 08:00 German time sharp for at least nine hours or until you "finish the daily tasks". Pay would however be for 189 hours per month, no compensation for sick leave/holidays/vacation, and you'd be paid via upwork.com (with you paying Upwork's fees) in US dollars.
