A good sign for workers here (8)
I believe the answer is:
apiaries
'workers here' is the definition.
(an apiary contains bees - worker is a type of bee)
'a good sign' is the wordplay.
'good' becomes 'pi' (I've seen this in other clues).
'sign' becomes 'aries' (star sign).
'a'+'pi'+'aries'='APIARIES'
'for' acts as a link.
(Other definitions for apiaries that I've seen before include "Places where bee-hives are kept, honey farms" , "many buzzers!" , "Places where bees are kept and nurtured" , "Strange sepia air for the Apis families" , "Bee houses" .)
