One day the workers at a factory are called together and told by the management that the factory was going to full automation. Everyone would be retrained to maintain the automated manufacturing equipment; no one would be fired and there would be no reduction in pay or benefits. But workers would only have to come to work on Tuesdays to do the maintenance; the rest of the week would be their own time to do as they wish.
And from the back of the room came an anguished shout, "What! Every Tuesday?"
