You are wrong about working weekends. They were instituted by Henry Ford not the unions. Just another falsehood promoted by unions.
How the 40-hour work week came to be
During the Industrial Revolution, factories needed to be running around the clock so employees during this era frequently worked between 10-16 hour days.
In the 1920s however, it was Henry Ford, founder of Ford Motor Company, that established the 5-day, 40-hour work week.

Surprisingly, Ford didnt do it for scientific reasons (or solely for the health of his employees). Rather, one of the main reasons he came up with the idea to reduce the working hours of his staff was so employees would have enough free time to go out and realize they needed to buy stuff.
In an interview published in Worlds Work magazine in 1926, Ford explains why he switched his workers from a 6-day, 48-hour workweek to a 5-day, 40-hour workweek but still paid employees the same wages:
Leisure is an indispensable ingredient in a growing consumer market because working people need to have enough free time to find uses for consumer products, including automobiles.  Henry Ford
So the 8-hour work day, 5-day workweek wasnt chosen as the way to work for scientific reasons; instead, it was partly driven by the goal of increasing consumption.
