For what its worth, I love this job (ATCO) and all the ratings I use. I can't think of anything I would rather do. ..Well maybe a high class naughty film director. (Did I say that out loud?).
There is a lot of training involved, and annual checks for the rest of your career. But its a job that most enjoy getting up in the morning or evening (depending on shifts) for.
Money is ok. But although necessary, its not what motivates me.
