@meowski effectively there is a chance more than 80% of their jobs will be completely replaced and the dock workers aren't getting a lot of money so they are deciding to do a risky strike if they don't get 70% pay increase in the next 6 years and guarantee that a certain amount of humans have to work at the docks when they eventually add in a bunch of the automation.
If they strike for more than 3 weeks because they don't have any alternatives it will completely shut down most of the on-time delivery infrastructure and cause Nationwide chaos.
But a large majority of the dock companies have preemptively stopped a large supply of food and random items in anticipation of this strike.
