I'm halfway convinced that time-motion studies are some kind of demonic invention for exactly this reason. We can get 3% more productivity out of an assembly line, just by doubling the accident rate and giving every worker RSI! Goodhart's Law is dangerous even when we're making management and business decisions in good faith, but when ideas like "long term injuries are irrelevant" are implicitly added it becomes monstrous.
