I suspect working in an Amazon warehouse is much more physically intensive with commensurate increases in injuries and other job-induced ailments as compared to most retail jobs.

You are thinking of retail as cashiers, because that's what you see.

But a lot of retail jobs involve the stockroom with heavy boxes and crates, and a lot of bending and lifting to put products on shelves.

And much of Amazon jobs involve retrieving lightweight items from shelves to put in a bin.

The jobs are not that different.

Haven't they transitioned all their warehouses to the model where the person stays stationary, and robots bring product to the person? Or is that only in selected warehouses?

That's not to say standing in one position is any better or less stressful (might even be more so, if you've ever seen videos of the robots in action on the floor).

From the videos I've seen, different warehouses do different things.

I think that packing the shipping boxes is still all manual in all the warehouses.
