The "5 hours of work" suggested by kropotkin (I'm not certain which comment this is a response to so I'm assuming) is less a schedule and more a prediction of what is possible with an allocation of labour intended to benefit everyone.

One aspect of anarchism is fighting against alienation, which tends to be considered inherent in capitalism. Alienation from other humans (outside a personal circle) from competition and distraction. And alienation from "the product of one's labour", meaning that people rarely see any actual benefit from their work except being able to survive (at least simply put).

With a connection and sense of duty to other humans and the feeling that one's labour is worth doing, someone is a lot more likely to want to work for the purpose of getting work done (or altruism or solidarity). Labour wouldn't be compulsory and while their motive for not wanting to work might be questioned, someone wouldn't be starved for it.

Recommending literature is probably a bit blasé I really think conquest of bread is worth checking out if you're at all interested, it's reasonably short and pretty engaging (especially as far as 1800's writing goes).

(Also I'm still figuring stuff out so if anyone better versed wants to correct anything feel free)
