I would think that all regions will have the same set-up/job positions in the future.
Whole Foods has always allowed each region to operate fairly independently. I don't think that will continue much longer. I believe that all regions will operate identically, cookie cutter style.
Let's face it... The only way for Amazon to turn this ship around is to make changes to systems that, obviously, weren't working. Demo specialists have been obsolete, in several regions, for years. I am surprised to hear that there are regions that still have them!
No one knows what the future holds, but rest assured, there will be change.
Posted by @PxnlTUH-2vkd. Pretty much exactly what we are looking at. Our systems are so different region to region that there is no chance Amazon will not scrap the whole thing and institute a single system for the entire company (subsidiary?) And this will mean loss of jobs for sure.
