I remember learning about "Holy Monday" in the sense that it was known during the Industrial Revolution: Holy Monday did not only call into play the question of work time, but also the use of money, because workers did not return to work until they had spent all of their salary. From this period on, the slave was no longer considered simply a worker, but a consumer as well. The need to develop the internal market by opening it up to the poor had been theorized by Adam Smith. Moreover, as Archbishop Berkeley wrote in 1755, "wouldn't the creation of needs represent the best means of making the nation industrious"The resistance of the first factory workers manifested itself primarily over one of the rare things that belonged to them, and of which they were being dispossessed: their time. It was an old religious custom not to work on either Sunday or Monday, which was called "Holy Monday." Since Tuesdays were dedicated to recovering from two days of drinking, work would not reasonably begin until Wednesday. Wide spread at the beginning of the 19th century, this holy custom subsisted until 1914 in some trades. Various coercive methods were employed by the bosses, without success, to combat this institutionalised absenteeism. It was with the introduction of trade unions that Saturday afternoons off from work were substituted for "Holy Monday.'' This glorious conquest meant that the work week was extended by two days.
