The horror.
Several of us have served under OP-T skippers that lamented that they weren't selected as Operational Skippers, and openly wondered why, and what in their career they messed up to get OP-T vice Operational... There's also been cases of Ship vs Wing Command. The recent memo, especially since it was released after the previously disclosed command swap will only add fuel to the fire in those types of situations.
Unfortunately, PERS and leadership puts out the information and builds the collective knowledge that the board picks the best, most qualified individuals without bias. Now that the Boss says he can put people where he wants as he sees fit (which exists many other places in the Navy and in the outside world), the stigma exists that there is unfair, agenda driven bias and that undercuts the achievements of those selected by the haters.
