I think the answer is that it's not happening, at least not on too disruptive of scale. Sure, you'll get slower service here and there. Sure, you'll get isolated (but boosted to the top of every fucking media outlet) stories of everyone at a fast food joint walking out. But the country isn't undergoing some organic, informal general strike; that's not even happening in small pockets of it.

Note also that some companies are shrewd enough (and established enough) to cut back temporarily unprofitable services, blame it on "nO oNe WaNtS tO wOrK!11!", and delay the decision to re-expand until later. It's like that Citations Needed episode on Walgreens or CVS shuttering stores to reduce costs and then blaming it on shoplifting.
