>And his boss? “My boss is happy with the work I’m doing,” he says. “Or more accurately, the work he thinks I’m doing.”

This indicates that Gavin is accomplishing all of the tasks that his employer expects him to accomplish. If he's able to do this between the hours of 8:30am and 11am then how is it different from someone who takes from 9am to 5pm to do the same work? It sounds to me like Gavin has already taken an easier, perhaps lower paying position that is not very demanding on his skills and so he is able to complete all of his assigned tasks in a short amount of time and then play hooky for the rest of the day.

If he instead were to work the whole day it's likely he could complete 3 times as many tasks, do you think his employer would willingly pay him 3 times as much though?
