Worker who loads and unloads ships (9)
I believe the answer is:
stevedore
'worker who loads and unloads ships' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for stevedore that I've seen before include "he'll have loads on board" , "Dock worker" , "Unloader of shipping vessels" , "dock pay for him?" , "Dock-worker loads and unloads ships" .)
