Visa - free does not mean that you have the right to work, that's two complete different things.
I can travel to the USA Visa-free, but I can not get work permit!
Business travel and tourism, maybe possible, but right to work, I can promise you not a chance for the next 20 years!
Even if Turkey did join EU, they would still need another step to become members of EASA, and their regulations, where they would approve your qualifications!
Believe me, the grass is not that green here, given the chance I would rather go and live in Asia, than live here!
