I am good friends with someone who is now retired from owning Subway franchises. Over the years he tried rewarding good employees with more money. Every time he did this the employee simply calculated how many hours they needed to work to make the same take home they had before and asked to have their hours cut. So for the business this resulted in higher costs and a worse customer experience because the best employee was doing the work less often. Obviously, there's no moral problem with the employee deciding to work less, in fact it's just wonderful for them. But it's easy to see why employers see it as a net negative in many cases.
