You directly contradict your sibling post, which claims coming back is nearly impossible. Do you have many examples of people who have done this?
I should say I am the only person I have ever met in the biological sciences that has done this so it must be relatively rare.
I know that at Texas, in engineering (where I got my PhD) we had many, many professors with previous industry experience. I remembered thinking it was not nearly as terminal a decision as I had expected.
