I covered it below. I actually totally understand why it was ignored. I don't agree with the reasons, but I needed to accept them, anyway. I did what I could, to prepare myself, and my team, while still performing the assigned duties.
We did as well as could be expected. I stuck around, to the end, because it was my duty to my employees. My employers needed to deal with the problems they insisted on owning.
Just saying "I'm a strategic thinker" will turn off a large % of people. That's 101 as far as interacting with humans goes.
There's things I'm good at, and things I'm bad at. I don't shy from mentioning either. Anyone that has worked with me, is aware of how I work.
Feel free to judge me. You certainly won't be alone. I miiiiggghttt suggest maybe doing a bit of research, first. I make it fairly easy.
All I'm saying is what's been written doesn't read well. Most people won't research others, they'll just see what's written (or said) and if that is a turn off, they'll shut down. If you have good ideas it's worth taking a little effort to understand the machines and systems you are dealing with (humans and organizations) so you can get those ideas broadly understood/accepted.
I knew them, and accepted the fact they were ignoring over a decade (at the time) of working with me, so it was what it was.
We're usually really good at solving other people's problems, from outside, but every case is unique[0].
In the aggregate, I was proud to have worked there, and gladly stayed, even knowing what I knew, mostly because of the relationships I made, and the chance to learn what I learned. I was learning exciting new stuff; right up until the very end, and made many lifelong friends.
