Change is never neutral. And renewal is not the same thing as change. Sometimes it requires change, but not always and not in everything. There's changes that are needed, and changes that need to be fought against.
Too often in my experience organisational change is actually about entrenching the underlying existing power structure. While people are running around worried about their future, or irritated at losing things they valued, or scurrying for opportunity in the "new" system, challenges to those in power can fade away somewhat, troublemakers can be eased out, and hard won advances by people lower down in the structure can be clawed back.
Here's a link to a relevant song, - though I'm surprised the DT has it as "the Gallant Duke of York", when I've never heard it in my life as other than "the Grand Old Duke". Either way, he knew that a bit of pointless manoeuvring is a good way of keeping the troops from getting restive.
