There's probably some high bureaucracy workplace somewhere where only certain people are allowed to use the freight elevator but it needs to be used by others so much they just station someone who can use it there.
There are still elevators that you need to be certified to use like mine elevators, and other form of commercial/construction devices so you could certainly see an elevator operator existing in one of those places.
I know of an elevator that is also a ticketed access point to a stadium so the elevator operator also scans tickets and gives out wristbands. Very nice for wheeled accessibility.
