In or out (2,6)
I believe the answer is:
on strike
'out' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for on strike that I've seen before include "Refusing to work" , "Taking industrial action" , "Involved in industrial action" , "Facing a ball" .)
