Anything but a sign of legal workers (8)
I believe the answer is:
notaries
'legal workers' is the definition.
(I've seen this before)
'anything but a sign' is the wordplay.
'anything but' becomes 'not' (I've seen this in other clues).
'a sign' becomes 'aries' (star sign).
'not'+'aries'='NOTARIES'
'of' is the link.
(Other definitions for notaries that I've seen before include "legal professionals?" , "Legal clerks" , "Legal experts" , "Public officials" , "Legal officials" .)
