I have a friend that went from an engineering college degree to the leader of R&D in the Conoco/Phillips world to finally retiring early to become a consultant at $400,000+ a year with a corner office in a tower in San Diego.Of course it was a result of work ethic.
I learned my work ethic as a teen in the USAF,,,
Where if you didn't do your job you didn't get fired,,,
You got your rank and pay taken away and sometimes went to jail.
My point is that my work ethic wasn't what kept my job secure.
It was the fact that I took on tasks that no one else wanted to mess with,,,
And by doing that I became the only person who could do them.
No one in their right mind would fire the only person,,,
Who could manage/administer the on-line classroom platform during classroom shutdowns.
Becoming indispensable wasn't an accidental thing,,,
It was something I planned from day one of getting that job,,,
And I credit my good sense and forethought in providing for my comfy retirement.
Work ethic is important,,,
But being indispensable is better.

He took every crap job across the world that nobody wanted in the sand box, to Nigeria, to the North sea as a well completion engineer. Every move got him a promotion, until he hit Houston with 45 US patents to his credit and an office job. He got a reward for his work and had to give a speech at the annual shareholders meeting about 10 years ago.
He spent a lot of time, but got great stories to go along with it in those shathole countries, but like you, he made himself indispensable to that field.
He leapfrogged over a lot of his supervisors and survived the oilfield dips when thousands were laid off.
