Frank,
I fear you may have missed my point - if the weather was unsuitable, I didn't fly.
I did spend quite some time at Cabair, and I have also taught at about half-a-dozen other schools. At least Cabair have competent bosses and sound finances, and there was never any shortage of flying. They certainly never treated me like a child, and I accorded them the appropriate respect. I ensured I accorded respect to the AFIs working under/with me.
Bottom line - If I needed an instructing job again, I would be heading their way first.
You're right, I wasn't sponsored, but I know many who were, and they all have 'proper' airline jobs now, either as TP Captains or on jets, with good reputable companies. Bear that in mind.
Instructing can be very frustrating, especially if you view it as 'just hour-building for a proper job'. It is, and should be, more than that, and all instructors should discipline themselves on that point.
