And keep in mind that when there is an important backlog in the warehouse, new larger boxes are placed, covering the smaller ones that are hidden.That's because they're either on strike, covering for colleagues who are on strike, or trying to clear the backlog of work after a strike.
So, until the entire backlog is released, the small boxes do not appear.
It's not a joke, I was told and was shown around the local DHL warehouse by a manager during the pandemic delays.
