And if there weren't laws and worker inspections and whatnot in place already, people would go on strike - and that usually has a major effect, like nationally crippled transportation (of any sort) or rapid accumulation of trash.
Which TBF makes me a bit depressed about the Americans. Have all the Walmart employees unionize and go on strike - there's nothing the management can do, not even enforce their 'you cannot unionize' contract thing, if everyone goes against them.
Some people are afraid pushovers TBF. And the employers slowly turned them into that, by making them poor.
On the contrary. Walmart's policy to date has been to simply close the store:

They got in trouble for that one, so now they at least pretend to have other excuses:

I don't think you should lump the UK with the US on this one. You can't "just fire someone" in the UK, most employees can't work more than 48hrs/week, paying extra for overtime is standard, 28 days holiday is minimum¹ and taking it is normal, if you're ill you don't need to use a holiday day, etc.
The new-ish government website is a bit of a mess for linking to whole sections, but anyway: https://www.gov.uk/browse/working
¹ That legal minimum includes public holidays.
