Mondelez has been quietly closing sites in its DSD delivery model for years. I worked at a high volume, very efficient nabisco branch outside of the biggest city in WI for years until they shut it down in 2017. We were not the first closure or the last either.
We out performed the nearest branch annually. Its all about dollars & logistics in the end and they will say whatever it takes to keep you working there because they do need you to work until the end of the closure... then they dont. Meanwhile the upper echelon can keep collecting their bonuses paid for by the salaries of former employees.
