Hey mate, been valid tower and approach(without using radar) for just about 2 years and really just got the approach radar bit in the last 8 months.
Hard work, but really enjoyable courses. I started off flying and never thought I'd enjoy ATC till I (randomly)got into it.
Company paid for all of my training and got paid reasonably handsomely along the way too, so all in was really good.
Job is good fun, can be hard work, and it's the crap from the company that detracts from the job itself, but you get that in all industrys, so all in it's great.
Great job to get into. and for me it'll be a great fall back job if the flying doesn't work out. If I were you I'd just try and press on through the dark hours! Jobs are there eventually - from what I hear it's IR or bust though!!
Thing is ... I've got the flying itch back again! Bugger!! This will get expensive!!
