This is really absurd. Most janitors are paid by the hour. Why would someone engineer their paycheck away? You obviously don't want to spend a real long time doing your job less get fired or be seen slacking off. However if you were paid to clean a school after school and had a set task and you engineered a 4 hour job into a 1 hour job, EXCELLENT you just cut 3 quarters of your paycheck away. Why would you build a roomba when you can buy one? Have you ever used a roomba? You'd need like 500 of them to cover enough ground for a school or a store and they'd have to run overnight and avoid falling down the stairs if you were in school and good luck finding them all the next day. There's a whole custodial industry that has already thought of and solved many problems and perhaps they do things the way they do because that's the best solution, because roomba may be good for a room in a house but bad for a whole school If you had set hours, you still wouldn't want to optimize your route. I know that the time goes by much faster if I'm busy and doing work than if I'm sitting around with no work to do. Nobody wants to walk around and see employees sitting around doing nothing, that's a good way to get fired. People complain. Your hours get cut. Your paycheck gets cut. I had a job in high school that was awful because between the hours of 2 and 4 there was nothing to do. Two hours felt like a whole lifetime. I tried to make up work like scrubbing walls and stuff but I couldn't do that all the time because the walls were dirty once. It would have just been fine if I had some friggin work at that time.
