To be clear, Disney's middle management is one of the many victims here.
Corporate Disney has layers upon layers of management, so "middle management" covers a lot of ground.
However, the powers-that-be are demanding that this broadly-defined middle management figure out ways to quickly cut millions out of previously approved budgets. These middle managers are simply doing what they're being told in order to keep their jobs.
Guess what? If they protest or push back, they'll quickly find themselves on the street, replaced by someone who will make these cuts.
