The fight to discipline peasants into proletarians is indeed interesting. One of capitalism's myths is that it has reduced human toil yet Bushmen work two-and-a-half days per week and on average the working day was less than five hours.
In the Middle Ages hours of work was tied to the seasons and the number of holidays and fairs were many. Work was intermittent - called to a halt for breakfast, lunch, the customary afternoon nap, and dinner with also mid-morning and mid-afternoon refreshment breaks. The medieval workday was probably not more than eight hours. Days off in medieval England took up probably about one-third of the year. And the English were apparently working harder than their neighbors. In France they were guaranteed fifty-two Sundays, ninety rest days, and thirty-eight holidays. In Spain holidays totalled five months per year.

But for capitalism , there was a financial incentive to maximize the return on expensive machinery by having long hours, twelve to sixteen hours per day, six to seven days per week were practiced. Cottage handicraft workers learned to fear and hate factory work and its pace of work and degree of discipline. Clocks, not daylight or weather established work patterns. Workers often attempted to observed "Holy Monday" to lengthen the weekend
