Honest Frank,
I don't want this to develop into a slanging match with you, but I hope I can reply to one or two of your points.
Please bear in mind that I have been in the airline business now for several years.
First, let me say that I haven't been at Cabair for quite some years now, so things may have changed, but I did spend a long time instructing there and elsewhere from about '89 onwards.
You mention 'bully boy tactics'. Obviously you haven't worked for an airline yet, and when you do, you will find some of these tactics present in most of them. Read the other forums here.
Second class conditions - you're only a flying instructor, and you're lucky to be at a busy school with plenty of work about. When I say 'competent' I mean that the school will probably be there on Monday morning, and there will probably be students to fly. They can afford to maintain the aeroplanes and pay your wages.
If you can't approach your boss with a problem, what does that say about your personal skills? How will you get on at an airline where the problems are bigger and the bosses often more imposing?
The pay changes I can't comment on - I was well-paid whilst there.
Crew rooms? Go and check out your local 'flying school in a Portacabin' to make a comparison. I always found them quaintly attractive...
Food and drink moans... Are you going to join a 'low cost' operator? Take a bottle or a flask and stop being a big baby.
Gulping down your sandwich - well, I used to arrange my programme to cover a quick break by having a competent 12&13 student at lunchtime, say, who didn't need a lot of briefing, thus making time for a quick lunch. Perhaps that's not your style, but you do need to eat, so make time or run late?
Other duties? Show some commitment. I really do think you should go and try some other outfits on waterlogged grass airfields with unheated huts for offices and two run-down C-152s before having a go like this. What do you expect from your future airline employer? If you have a medical problem, they'll get you in to work doing menial tasks too, if the weather is too poor, you'll sit around on your back-side until Crewing tell you to go home (and you'll be taking your orders then from an 18-year old school leaver with no formal training to speak of who is effectively running your life).
I'm sorry to be so patronising, but my message is 'wake up and grow up'. If you need 'out' of Cabair that quickly, e-mail me and I'll do my best to help you out.
