I’ve worked at a company that did injection molding, and they made people have to work at superhuman speeds with equipment that continued to give injuries. Part of the reason is because they would collect data from the fastest person on the machine and expect everyone else to work as fast. The mentors who were being timed caught on and started working slower to make the pace less ridiculous. Management would also let go of people who had injuries because they didn’t want to pay for it.
