Occult sign for office workers (11)

I believe the answer is:

secretaries

'office workers' is the definition.
(secretaries might work in offices)

'occult sign' is the wordplay.
'occult' becomes 'secret' (synonyms).
'sign' becomes 'Aries' (star sign).
'secret'+'aries'='SECRETARIES'

'for' acts as a link.

I've seen this clue in The Irish News.
