> Or if you are a taxi driver working with half the day spent waiting for a fare. This is a good example. Suppose the driver spends 4 hours waiting for a fare out of total 8 hours working day. Now, they obviously cannot reschedule their time as to drive 4 hours non-stop and then take 4 hours off. In that sense waiting for a fare is also work. I would define work as everything that holds you back from doing non-work.
