Well that's part of the problem. It's hard to pin down who is and isn't coming to work. I get shipments of material delayed (CNC Machining business) indefinitely, holding up production. People don't show up to work for one reason or another, and material delays because maybe a trucker calls off sick or something, you can't account for all of these variables. You can know how many man hours it takes to build a transmission, but if your castings are late and then people don't show up to your factory, you can't translate the man hours into a schedule like you could before.
