How many times have you seen 10 workers standing around one hole in the ground. . . one to drive the truck, another to drive the crew, one to carry the equipment, one to supervise the crew, two to actually do some digging, one to evaluate the situation, one to clean up the debris, another to drive the truck that the debris has been put into, one to carry the equipment back to the original truck, and another to call it quits.
There’s an old joke that the state highway department is going to lay off 3,000 highway workers because someone in Germany invented a shovel that can stand up all by itself.
