You get employees to care by compensating them well for the job they do. This compensation isn't always money. It can be money. It can also be good benefits.

You get employees to care by compensating them well for the job they do. This compensation isn't always money. It can be money. It can also be good benefits. It can also be interesting work, but working in retail is inherently non-interesting for most people. So basically when it comes to retail the way to go is to provide good employee compensation and/or benefits. With some notable exceptions (eg. Costco), very few retail employers compensate their employees well, so of course the employees aren't going to care about their jobs.
