Actually, I was aware of the stated production goals. I watched employees who were working at a pace to meet that goal. Pretty pleasant environment if you ask me.
Just a couple examples of my perspective:
I recall a commercial bakery I worked in the summer after Highschool: Temperatures outside were over 100° F, temperatures INSIDE with the commercialy sized Proof Box and Oven were considerably higher. It's loud because of the machinery, so you're wearing earplugs. You have to wear a hard hat, and a hair net. There's Flour floating in the air, and since you're sweating profusely, it sticks to your skin and makes a paste that sets up. You can't drink enough water that you'll have to pee during your shift, you just sweat it out. All for a comparative wage and benefits package well below what people working in the Amazon Fulfillment Centers command today...
I remember when I had my own business: Imagine unloading a 53' semi dry van at temps well below 0° F, and I'm talking boxes weighing several hundred pounds, to over 1000 pounds for fire safes. Or doing the same thing when it's over 110° F outside, but in the trailer baking in the sun, it's over 140° F. And we're not talking unloading at a nice finished Dock. No were talking at a building that might still be under construction, and you have to haul the items over paths in the dirt, to get into a building through doors only meant for people, and down halls with construction debris all over, and a light bulb illuminating the way occasionally.
Amazon Fulfillment Center workers in their cushy climate-controlled environment feel they deserve better? Cry me a river.
