I worked there as a contractor before 9-11.
First day my contact ask if we could meet in the smokers pavilion, so he could have a puff.
The huge monster ash tray was overflowing with butts! He said they clean it every two hours,
The controllers work one hour on, one half hour off; to rest the eyes. The last hour go home paid,
Some run FULL TIME businesses on the phone while at work.
A controller told me that he did the same job in the Navy. He said it does strain the eyes but the Navy had a different schedule. On duty at times it went ‘hot’; you did not think of getting up, for hours.
The overnight cleaning crew used something that had an odor .
They shut it down for hours to air it out and make it safe!
The computer still used wired core memory and a punch card reader! A new system was on the way so they gave early retirement to the guys that kept the dinosaur alive.
The new system was delayed so the had had to hire the old guys back $$$ plus the pension to feed the beast.
Many good and talented people work there but also some stand out prima donnas and slugs.
Sounds like an IBM 1620.
