See I think you're just proving my point. It's such a great opportunity that nobody in their right mind is going to pass it up, since they haven't really been shafted... yet. In comparison with going to a CTI school or serving in the military, you never dreamed about being an FAA controller for years and making good money. You never had to be told "well, no, i know we told you you'd be making this... and we've known that wouldnt be the case for a while, but we never informed you. OH AND BY THE WAY, we're hiring people without any aviation experience whatsoever now... even though we told you that the only way to become a controller was to go to one of our ridiculously expensive schools or join the military. Good Luck!"
So in that respect, I think OTS is kind of putting a damper on negotiating better pay--but through no fault of the applicants.
