Pass fellow work note (4,3,2)

I believe the answer is:

dont ask me

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

'pass' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'fellow work note' is the wordplay.
'fellow' becomes 'don' (both can mean an academic).
'work' becomes 'task' (task is a kind of work).
'note' becomes 'me' (alternative spelling the musical note mi).
'don'+'task'+'me'='DONT ASK ME'

Can you help me to learn more?

I've seen this clue in The Times.
