I can only speak on what former TSA guys have told me...and none of them were happy. Lots of bitterness regarding management, not so great on the work rules, the whole issue with GoJets, etc. All of them used the job to get on with a "better" regional (for lack of a better term). While I never personally worked there, everyone I do know who worked there got out to go to another regional (Xjet, CHQ, Air Wiskey etc.) If you can make the same amount of money as a CFI (shouldn't be too hard against first year FO pay) then I would do that instead. Better QOL, home every night, and you're still giving up the seniority when you switch jobs later. The one bright spot I hear is the pilot group is pretty cool group to work with.
