I would add that Amazon is extremely innovative in ways to make warehouse employees more productive. They are physically limited in how any employees they can fit into a warehouse, and what geographic region those employees are hired from, so they have to make sure these employees are productive because they can't just hire twice as many to get through peaks if they aren't productive enough. At the same time, these employees are treated poorly and are peeing in bottles while standing at their station because Amazon didn't account for the physical need to urinate. Facebook has none of these restrictions, and these employees don't even work for Amazon, and they are behaving the way you would expect a company to behave with these incentives.
