You are a manager at an electronics store. Tal is an employee at the store. Until recently, Tal was a good employee. This past month, however, Tal has started coming in late, complaining about work, and looking unhappy. You have noticed Tal spending less time on the floor helping customers and more time sitting around in the stockroom. You approach Tal to talk about the problem. Tal tells you that until last month, employees earned a commission for every large appliance or electronic device they assisted a customer in selecting. Now a new policy, just announced, eliminates commissions and instead, all employees get a small hourly raise. When you ask if this is the reason Tal's performance has declined, Tal gives a shrug and says, "if that's all, I'll go back to work now."

Briefly explain why the framework you chose is most relevant and applicable to the problem as you've framed it.
