Short point: I once had occassion to attend a (Marxist) Longshoreman Union's meeting. They ranted on and on about how (Marxist-backed, please read history) Unions are responsible for giving American workers their weekends. I beg to differ. Please read the 4th Bidding of God (Fourth Commandment). The reason Moses implemented that, at least in part, was as a burst of FREEDOM to the long-oppressed inhabitants of Canaan who had been previously worked CONTINUOUSLY, without stop, by their wealthy Ba'al worshipping Canaanite owners. By setting aside a "Day of Rest", Moses thereby assured that the monied land owners could no longer unflaggingly work their peasants to exhaustion and beyond. So if you ever hear a (Marxist) Union speaker claim (Marxist) Unions gave you your weekend, please find the strength to point out that MOSES beat them by about 3K years.
