Stop work and steal (5,3)
I believe the answer is:
knock off
I believe this is a double definition.
'stop work' is the first definition.
(I've seen this before)
'steal' is the second definition.
(I know that knock off is a more specific form of the action steal)
'and' is the link.
(Other definitions for knock off that I've seen before include "stop, > take away and > kill > pirate" , "half-inch > pack in work" , "Do quickly" , "call it a day" , "Down tools" .)
