Yeah union jobs definitely seem to get all the safety aspect down in my experiences in the US. In some cases in can be a little overzealous, but 99.99% of the time you want to be doing what they recommend and have the tools and safety gear they expect so you don't get maimed or killed just to save somebody else 30 cents. That isn't to say you can't find safe non-union work, but generally you gotta do a bit of job hopping around in most trades to find a safe employer because doing unsafe shit is all too uncommon in trades.
