Why the shelf boundary has to be written down
Verbal arrangements about stock fail on the first staff change. One cleaner assumes tidying is helpful and squares up the boxes; the next assumes nothing on a shelf may be touched. Both are guessing, and the store notices the inconsistency long before anyone raises it. Writing the rule removes the guesswork and gives the retailer something to point at when a new crew member starts.
The wording that works is physical rather than abstract. Clean the floor including under the lowest shelf where reach allows. Clean exposed shelf edges and uprights. Do not lift, slide, open or rearrange anything stored. Do not clean a shelf section that has stock on it. Report anything that has fallen, split or leaked. Those six instructions cover almost every situation a back room produces.
