Auntie's boss precise or vague? (8,7)

Ross

I believe the answer is:

director general

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

'auntie's boss' is the definition.
The definition suggests a singular noun which matches the answer.

'precise or vague?' is the wordplay.
'precise' becomes 'direct' (I can't justify this - if you can you should give a lot more credence to this answer).
'vague?' becomes 'general' (I've seen this in another clue).
'direct'+'or'+'general'='DIRECTOR-GENERAL'

Can you help me to learn more?

(Other definitions for director general that I've seen before include "chief executive" , "Head of organisation" .)

I've seen this clue in The Times.
