wasn't the situation then that the air traffic controllers walked off on strike, so new replacements had to be made to keep planes flying, which was realized by firings? (i was pretty young then, but that's what i remember reading)
IIRC, rather then negotiate with the experienced union controllers until an agreement was made - they brought in inexperienced non-union controllers..
source: my uncle was an ATC during the strike. I believe he was a shift lead/supervisor and was NOT part of the walk out. He was appalled at how bad the replacements were and was going crazy trying to get them up to snuff.
