Training a controller from scratch is much more effective than picking up someone who is no longer a controller due to stress, etc. It’s not exactly a 2 week on the job course. There are waiting lists for ATC training in many cases, and a small percentage of applicants even make the cut to start training.
You’re exactly right, AAIE.
Shame on you! You should know that there is this element on FR who know better than FAA management as to how to recruit for their employees.
