They cut the wages of the shore workers (7)
I believe the answer is:
dockers
'workers' is the definition.
(docker is a kind of worker)
'they cut the wages of the shore' is the wordplay.
I cannot quite understand how this works, but
'cut' could be 'dock' (docking is a kind of cutting) and 'dock' is found in the answer.
The remaining letters 'ers' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for dockers that I've seen before include "their harbour operations?" , "Cutting short" .)
