If this "retrain" rate is true then it's higher than anytime in the history of UAL. This includes when we used to have to "build" the airplane through orals and such.
Basically I have a really hard time believing those numbers and would ask what "retrain" means and how many are unable to complete in the required number of hours.
The FAA does monitor all approved training programs and when the recheck, exceeding hours required and other "retraining" issue happen they put the program under the microscope. The FAA also has the opportunity/ability to step in and take over the program if it is having problems.
Again, especially considering the experience level of today's new hires, I really have difficulty believing this. The LCA probably heard it from a F/A who's boyfriend/significant other/husband/wife told them.
