I've been on the receiving end of middle management because I've been able to fix things in the business that have always been broken but never got fixed until I worked on them.

Management will claim it's their work, will give you just lip service, will not use your name higher up the hierarchy and will actively down play their own mistakes whilst blaming the rest of the department or developers (e.g. like building a project with wrong requirements they actually provided, then missing the deadlines because stakeholders demand changes).

Where that has happened I quit and then they just go back to the status quo.
