I mean, presumably Wal-Mart has excellent statistics on "shrinkage" from regular inventory checks like any store, as well as recording how often shoplifters are caught, and so they have clear data as to whether or not Everseen is an improvement or not.
And I don't understand what this has to do with COVID-19 at all in the article.
Finally, what do employees care about theft? It's not coming out of their paycheck. False positives from an anti-theft system seems like a small job nuisance at best -- not something to whistleblow with a "slickly produced video".
Nothing about this article makes sense to me, unless it's motivated by an Everseen competitor -- whether another company or an internal division of Wal-Mart that thinks they have a better solution. In either case, why would the general public care at all?
