Pointers for the workers (5)
I believe the answer is:
hands
I believe this clue is a double definition.
'pointers' is the first definition.
(hand is a kind of pointer)
'the workers' is the second definition.
(hand is a kind of worker)
'for' acts as a link.
(Other definitions for hands that I've seen before include "Workmen" , "Units for measuring horse's height" , "Crew members" , "Passes" , "Measurements for horses" .)
