Don't touch: the workers are leaving (5-3)
I believe the answer is:
hands-off
'don't touch the' is the definition.
I can't judge whether this definition defines the answer.
'workers are leaving' is the wordplay.
'workers' becomes 'hands' (hand is a kind of worker).
'are leaving' becomes 'off' (as in 'I'm off').
'hands'+'off'='HANDS-OFF'
Can you help me to learn more?
(Other definitions for hands-off that I've seen before include "With no manual input" , "Not involving any intervention" , "Don't touch!" .)
