Some things never change. In the history of ATC, one moment recruiting has been put on hold due to staff excesses, staff forced to take rec leave, special projects (etc) , next thing, mad recruiting, qualified overseas and military candidates being sought. (12 months + lead time)
Funny thing though, the current crop sitting in the ATS Management seats, were the ones 10-20 years ago that were on the receiving end of what I described (above), and thought they had all of the answers if they were ever given these positions (which they now hold). !!!
