Quoting as739x (Reply 3): The stations are staffed by a AS Station Manager only. The rest of the staff is contracted. Some stations will share a Station Manager. MSP manager use to over-see another station in the beginning.
Stations with outsourced Customer Service functions now have a CSL (Customer Service Lead) which is a AS union position. They basically handle supervisory functions. This frees up the Station Manager to possibly oversee another station as well.
