This is a recurring pattern now - over and over.
I take up a typical contract offer - I figure out the technology and environment way faster than others (and usually way better than those who have been there for years).
This leads to all sorts of issues as the more established bums on seats start feeling threatened.
They happily extract as much as possible from me (solutions, insights, knowledge - which I freely document and share) but I am then accused of not being a "team player" (which I realise is a euphemism for: either don't see through all the BS or if you do, just play along. "play the game").

How does one break in to a more niche and specialist type of contracting (if it exists) where one can "get in, get the job done, get out" and not have to deal with all the unnecessary baggage.
