I believe the answer is:

supervision

I'm a little stuck... Click here to teach me more about this clue!

'oversight' is the definition.
(I know that oversight can be written as supervision)

I can't explain the remainder of the clue.

(Other definitions for supervision that I've seen before include "Control" , "Oversight" , "provided by the boss" .)

I've seen this clue in The Globe and Mail.
