Stop and fire (3,3)
I believe the answer is:
lay off
I believe this clue is a double definition.
'stop' is the first definition.
(I know that stop can be written as lay off)
'fire' is the second definition.
(I know that lay off is a type of fire)
'and' acts as a link.
(Other definitions for lay off that I've seen before include "Give over!" , "Stop - cease to employ" , "Hedge (bet); suspend (worker)" , "Temporarily discharge (workers)" , "Redundancy" .)
