Please don't stand on the base deck. Not only does it damage the deck (causing endless headaches for reset teams) but you risk tipping the entire gondola over on yourself. I have seen serious injuries from this.
The stores I do all have 6 feet or higher shelves.
I suppose I shouldn't take for granted that everyone understands the structure of a base deck and where it is safe to stand without damage or injury. I don't service any stores that have gondolas so unstable that weight on a bottom shelf would flip it. What types of products do they sell? How do they move product for resets without tipping them over?
