The controllers are represented by a union, which can hopefully have some influence. To further complicate things, some controllers are not govt. employees, they can also be state or municipal employees. In all the years I have been a pilot, I have never been able to tell what controller was wearing, as I only interacted with them on the radio.
Thank you for your observations and insights, Jerry.

I have deleted my post.
