It is an interesting circle though. "We still treat people as though they are doing one-dimensional work (like moving something along an assembly line), when for most of us work is complex, ever-changing, and multi-dimensional."

That is the danger in bringing coaching in-house as well, in that by default with the mind-set of "let's scale it", management's approach is "standardise it"! Internal Coaches would therefore be in the same risk of being put on the hamster wheel (as you rightly point out that is why they are not likely to go for the opportunity).
