15 years ago, Circuit City laid off their highest paid retail employees, to be replaced by new hires: https://www.nbcnews.com/id/wbna17837882

That is, management was declaring that there was no value in experience whatsoever (until you got to management levels, naturally), and that they could replace anyone with a new hire without loss of performance. (After all, the way you got to be a highly paid retail person was to stick around for a long time and be pretty good at your job.) And while most managers in a retail setting aren't quite as obvious about it, that sure seems to be how they feel: employees are completely fungible, and it isn't worth paying them enough to get them to stay.

(Costco is a notable exception in the US: notice how the standard Costco name badge includes their start year on it, that is one of the ways Costco signals that they do value experience. They are also significantly more profitable per sq/ft than Sams Club, their competitor in the warehouse segment operated by Walmart. I strongly suspect that those two facts are related.)
