This is very nice of the owner, but extremely inefficient economically. Which means most companies can't afford to do something like that. Only if your profit margins are huge.
Like Amazon, Facebook, Google, Apple or Microsoft?
For Facebook, Google, Apple and Microsoft, not much would change, they don't employ that many people below the threshold, I think, unless you count the outsourced contractors that do moderation, annotation etc. This company's policy doesn't extend to the company they outsource the cleaning of their office to either, so that wouldn't be a fair comparison.
