Get out of work, having to take part in strike (3,2)
I believe the answer is:
hop it
'to take part in strike' is the definition.
I know nothing about this answer so I can't judge whether this works.
'get out of work' is the wordplay.
I cannot quite see how this works, but
'of' could be 'o' and 'o' is found within the answer.
'work' could be 'pit' (pit is a kind of work) and 'pit' is present in the answer.
A single letter 'h' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'having' acts as a link.
Can you help me to learn more?
(Other definitions for hop it that I've seen before include "split" , "Get away!" , "Scram!" , "Skedaddle!" , "shove off" .)
