I was lucky - I went to an airport on OJT where I was very well treated and learned a lot from my six weeks. In fact I'll tell you where - Birmingham
However, it's not easy to stay motivated when the more disgruntled members of the ATCO community continue to slag off CATC. More than once have I been told (not particularly on Aerodrome OJT) that the only thing CATC was good for was to teach RT discipline and the rest was worth forgetting - even then you get laughed off the face of the earth the first time you say "one Tousand" :-)
I do agree though that some people go to OJT thinking that just because they hold a student licence that they are the mutts nuts. I think students should be reminded before going on OJT that they are still a loooooong way from becoming a valid controller. And maybe if OJTI's were rewarded more they would once again become tolerant, caring mentors to us poor chaps and chappesses learning our trade.
