Let's play this out - imagine they implement this. They spend millions (realistically tens/hundreds of millions) putting up sensor systems, spinning up data center capacity, hiring analysts and all the auxiliary work that goes along with this sort of program, all for what - to further dehumanize some poor middle age single mother who's making $9 an hour? And for what -to optimize some stupid metric?

Walmart would be far better off putting that money into the wages of their lowest paid employees, or investing that money into manager training and giving people on the ground help.

In my mind this is where inequality really starts to bite - this level of surveillance at work is disproportionately aimed towards those with the least power and agency.
