So you want a written guarantee that the boss will hire you back IF you decide you don't like the airlines. I suppose you would support a written agreement for the pilot to guarantee his return to the job and leave the airline correct? I mean this boss has held the position for that pilot for 2 years right, so not giving someone else a shot at the job.

Seems like the poster needs to make a DECISION about which road he wants to take and then press forward - with all of the chances and choices such a decision entails.
