I have, on multiple warehouse floors, for around 3 years cumulatively.

Meanwhile, it's obvious you're projecting your own inexperience. Maybe you're the one who should actually set foot in a warehouse before commenting.

Then I'm sure you'd consider any job away from an air-conditioned office to be terrible.

Warehouse work is certainly hard work; picking and packing certainly entail being physically active. I won't pretend it's immune to asshole bosses or that injuries never happen; that's the nature of manual labor under capitalism. It's still vastly preferable to outright abusive job sectors like retail or restaurant work or customer service; I'll take walking 5+ miles through a pick path or packing 50+ boxes all day (even with leads and sups breathing down my neck over my numbers) long before I'd consider subjecting myself to snotty asshole customers berating me over their own ineptitude.

Amazon is the exception, not the rule. Warehouse workers outside of Amazon could certainly be paid better - all workers could and should, in many many sectors - but this assertion that a megacorporation with a specific reputation for abuse is somehow representative of an entire job sector is one of those baseless assertions that demonstrates considerable ignorance and inexperience.
