That's not an inevitable property of the universe, that's a culture. I did tech at a mechanical/electrical/plumbing contractor called US Engineering in KC. The union (unions?) and Corporate worked pretty well together, because they had to. Aggressive subcontractor bidding means you only get a few percentage points of profit on each job, the unions fight to get their fair share knowing that if they fight too hard they make the company brittle and they don't want the company to fold, indeed it was kind of shocking to hear people taking some pride (even in jest) at making the CEO and his family some cash. But the biggest thing was, Believe In Zero. Huge push, lots of concerns that all of the new hires in new regions working on data centers did not understand this long-held cultural expectation. It's to believe in zero “unsafe behaviors,” things like turning with one foot when you get off a ladder (instead of planting both feet on the ground and then turning). Even if “Believe In Zero” was the corporate side, the unions were committed to “yeah that's what we do” and typical welders would remind me that they are working with thousand pound plumbing assemblies, cutters that need to slice these massive pipes open, and of course day-in-day-out they are going to be staring at the plasma of a welding torch melting this stuff back together—“all any of us want to do is to have some pride in our work, get a fair paycheck, and get home safe and healthy,” they'd say. Why would Corporate care, why would the unions push so hard for how you step off of a ladder? Because if you roll your ankle or yank the ladder towards you, could create an injury, that requires paperwork for OSHA, then the insurance company will look at that paperwork to try and argue that they should get more money because you are not a five star super-safe workplace, even if they are not paying that much for the actual incidents. And when your margin is only a couple of percentage points, you can't be spending half of it on insurance. So they did. Heck even I got into it. One thing I did to “Believe In Zero” was to cover up all of the exposed nails or splintery plywood in the corner where we stored soda. Sure “no reasonable person is going to run their hand across these surfaces”, but hey, you never know, maybe someone spills a coffee and someone else slips on it, if it's just 10 minutes for me to fix it now, and I can be thinking about how I want to structure a module while I am doing it, why leave it?
