Amazon begins temperature checks and will provide surgical masks at warehouses

"The company will also use machine-learning software to monitor building cameras and determine whether employees are staying at safe distances during their shifts, or whether they are often huddled too close together"

I can see that working in tandem with some kind of alarm or alert sounding when workers are too close together. The second order effect, would be some kind of Pavlovian response in Amazon warehouse workers even beyond this physical distancing period.

That's the kind of stuff you used to read in sci-fi novels.
