"over-stressing workers and pressing them to be as efficient as possible, causing them to cut corners with safety" is such a universal point of failure that it's frequent in every modern industry and a contributing factor in a huge number of workplace incidents and industrial disasters. respectfully, you would have to actively ignore reality to hold the position you currently do, and if you think that's the worker's fault and not the company incentivizing them to do unsafe things to keep their jobs, i can really only describe you as a corporate apologist or bootlicker
FWIW I've been a mechanical engineer for decades and they are right about this. Trust me instead. They're probably reacting with hostility because you're way out of line here; what you're arguing is anti-labor.
There is a profitable balance between productivity and safety, and they'll say one thing while firing people who are too unproductive.
Oh so your experience matters, but mine doesn't? I've presented the same quality of evidence that you have. There isn't a worse "look" than tirelessly arguing that labor is at fault for what we're de facto forced to do.
