Worker a little attractive (8)
I believe the answer is:
handsome
'attractive' is the definition.
(I know that handsome is a more specific form of the attribute attractive)
'worker a little' is the wordplay.
'worker' becomes 'hand' (hand is a kind of worker).
'a little' becomes 'some' (both can mean a small amount).
'hand'+'some'='HANDSOME'
(Other definitions for handsome that I've seen before include "Easy on the eye" , "Pleasing in appearance" , "Goodly" , "Nice-looking" , "Attractive in a strong, imposing way" .)
