In my history, before finding my terminal career, I worked retail management. I worked for a chain that is no longer open, so I'm fairly certain I can say whatever I want about it now.
I was fast-tracked for upper-level corporate management (I think it was the combination of not-giving-a-fuck based on depression and low-grade sociopathy that did that). During this process we were asked to optimize a store in our region. This optimization process included outlining for store staff the process to remove "internal shrink" read: employees stealing.
One of my stores had the highest "internal shrink" and "employee arrests" in the entire chain. My solution was to make a differential pay scale for that store. I increased all wages across the board by $3/hr up to the store manager level.
"Shrink" stopped in the first month. Not just "internal shrink" but external as well. The employees were actually NOT stealing and ACTIVELY stopping people from stealing.
I was told it wasn't as cost effective as installing cameras in common theft areas and outsourcing security to a third party, and it was scrapped after a year.
That was when I decided to leave retail and the corporate world in general.
