Work in a supervisory role, like a bishop? (7)

I believe the answer is:

oversee

'work in a supervisory role' is the definition.
(overseeing other employees)

I don't understand the rest of the clue.

(Other definitions for oversee that I've seen before include "take charge" , "As supervisor does" , "guide" , "Supervise, manage" , "risk eyestrain?" .)

I've seen this clue in The Guardian.
