Good market for flying instructors and if you're willing to put in the hours and get up to Multi-IR Instructor level you'll be in a fantastic position to negotiate a good deal as there is a bit of a shortage of them out there...
At PPL and CPL level, PTC, NFC and Atlantic Flight Training in Cork all have a large number of students passing through the doors so the market is definitely there. Obviously America is a more lucrative market but if you wanna stay in Ireland I'd say your job prospects are good...
