This is standard for companies like this. Caterpillar does this as well. Cat has prepped for this before and come very close to implementing it. Last time they did it, that I can remember, was in the 90’s when the union went on strike. They don’t just turn the engineers lose on the floor, they provide training and get them able to do production.
It’s a contingency plan, and if it happens, it won’t last very long.
John Deere also did this in 2021, and they managed to immediately crash a tractor on day 1
Another fun approach is to work as slowly as possible, under the excuse of “I don’t want to damage valuable company equipment or risk downtime due to injury”.
And then sue that you were injured in a role you weren’t hired or trained.
