Good-looking workers love yours truly (8)
I believe the answer is:
handsome
'good-looking' is the definition.
(synonyms)
'workers love yours truly' is the wordplay.
'workers' becomes 'hands' (hand is a kind of worker).
'love' becomes 'o' (love means zero in tennis).
'yours truly' becomes 'me' (the person that set this crossword).
'hands'+'o'+'me'='HANDSOME'
(Other definitions for handsome that I've seen before include "Pleasing in appearance" , "Good-looking, as a male say" , "large" , "'Good-looking, as a man might be (8)'" , "Easy on the eye" .)
