Which is the problem. We're trying to say we've generally exhausted our productive capabilities after 4 days of work per week, which is what this article was saying as well.

If I've contributed my maximum amount in 4 days rather than 5, it should not be called part time. Part time should be reserved for instances where you are indeed contributing less than a full amount per week, such that you could hold two part time jobs.

Well, if enough people do it then it will be full time. It's more about what is considered to be the norm than anything else, and of course you will get paid for four days, not five. But over time pay will go up again and then we can repeat the cycle with three days. The interesting question is not 6, 5 or 4 but what the lower limit is. I suspect still quite a bit lower than 4.
