Also to your other part about "it's not that hard"

It actually is. We cannot get enough bodies in the mill to not work everyone at full time. We pay 18 year olds 6 figures to operate a mill and we still cannot get enough bodies to come anywhere close to working a 4 day week.

It straight up doesn't work that simply when you're running enormous 24/7 operations in critical industry. Thats like all the football fans on the couch yelling at the coach "JUST DO X". Really easy to say "do X" but the application becomes extremely difficult. Yeah in an office, sure....in a refinery where you create base stock products that allow hundreds of other major plants to run to produce all the basic products you use every single day? Not gonna work that way

This isn't some machinist shop that takes orders. it's a multi billion dollar full rip steel mill/refinery/plant/etc. that loses LOTS of money when it's not at full capacity. That has lasting knock on effects on other industries for example when base manufacturing can't keep up
