Some of the hired staff are ruddy radical! (4)
I believe the answer is:
reds
'some of the hired staff are ruddy radical' is the definition.
I can't judge whether this defines the answer.
'some of the hired staff are ruddy' is the wordplay.
'some of' says the answer is hidden in the clue.
'REDS' is hidden within 'hired staff ruddy'.
Can you help me to learn more?
(Other definitions for reds that I've seen before include "First snooker balls to be potted" , "Left-wingers" , "Scarlet and crimson, say" , "Tidies up" , "These are not right" .)
