They take minutes to make hidden ram (11)

I believe the answer is:

secretaries

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

'they take minutes to' is the definition.
The definition suggests an adverb but the answer is not.

'hidden ram' is the wordplay.
'hidden' becomes 'secret' (I've seen this in another clue).
'ram' becomes 'aries' (I've seen this in another clue).
'secret'+'aries'='SECRETARIES'

'make' acts as a link.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
