That suggests precheck is a rubber stamp. Does nobody get rejected?

I'm sure people get rejected from precheck. I doubt that people rejected from precheck would take up a job where they have to travel on a plane four times a week on average (or rather, they travel enough that they go through a full-body scanner four times a week).

As far as I understand, precheck is not a rubber stamp - it is a shakedown.
