Center Sup is the worst job in the agency. It's why so many centers take the super inexperienced people, or the worst controllers from the center. Very Very rarely does a decent disillusioned controller bid a Supervisor job hoping to enact change and improve things.
Only later as they endure the crushing defeat of discovering that they now get shit on from above and below, forced to a crappy schedule because of their lowly supervisor seniority. Resenting their peers who spent no time in the realm of controlling traffic, but instead all of their time watching others do said work, as they discover actually working means nothing in the MSS career fields.
If the Controller is lucky it was a temp bid and they can slink back to the floor with the experience and stain of their terrible decision. If it's permanent they are doomed to imbibe in kool-aid until nothing is left of their former self. On their death bed they will reflect how this was worst decision they ever made in their lives.
It's a Trap!
