Lying down on the job

My job can literally be a pain. Reaching up on the top shelf to bring boxes or cans is not so bad. Bending over to put things on lower shelves can be a bit awkward at times. But seeing what is in the back of the bottom shelf preventing you from stocking an item can be a real pain in the back. The most effective way and the least painful involves lying down on the floor so your eyes are parallel to the shelf. But at my age getting back up can be either slow or painful, depending on how far behind I am.
