Where on earth did the author find this revisionist nonsense? The 40-hour work week was won after a bitter decades-long fight by workers and unions against business owners. The idea that Ford bestowed it upon a grateful staff to improve capitalism is wrong, pointless and insulting. Here's an article in favour of shorter workdays that takes history a little more seriously: http://www.iww.org/history/library/misc/Bekke…
By the way, it's also quite laughable that you're citing a blatant biased piece from a union website. Please tell me you're just trolling.
