Flexible ? . . . Hmnnn?

may be , you will not be best served looking at Turkish/Turkey,
AFAIK & as far as I have seen, flexibility is a bit of a one-way-street ( = be prepared to bend over ! )
Many of the threads on here relating to pilots conditions & adhering (or rather failing to ) the conditions of the "contract"

would, I suspect, be equally applicable to the Sim jobs.
The TRI position may well be regarded differently by the Turkish CAA. As far as I could see, despite being supposedly JAR, they regard/disregard which bits are convenient or otherwise, so all & everything possible.
Best of British if you go for it, better man than I am Gunga Din.
