It's disgusting that 3hrs a day is acceptable...when I trained (at two Zs) I personally thought anything less than 4 was a bad day...regardless of what certs I already had. A lot of trainers here don't seem bothered by taking every break offered, even if it means skipping busy traffic: I've routinely said "Where's a training team when you need one."
My area has someone who has no business being a controller. They were up to their last dozen hours on their current position, and are back to article xx hours. They already had free hours after the last covid training stoppage. Person barely gets any consistent training or even asks to be trained, and when they do, are trained by the one person in the area who scarcely writes anything on training sheets. Even if they went to a TRB, they are coming back; a supe failed to give them a skills check 9mos ago. This person is already a shitbag controller (who has long since proven the ability to drag down the performance of those around them), with a shitbag attitude, but unfortunately they are going to keep getting hours until they get certified becuase no one can follow whatever proper procedure is at this point.
It's interesting that I've heard more of the "process" protecting these types, versus those who put effort in and honestly try.
