Tired men at work stopped (10)
I believe the answer is:
terminated
'stopped' is the definition.
('terminate' can be a synonym of 'stop')
'tired men at work' is the wordplay.
'work' indicates anagramming the letters.
'tired'+'men'+'at'='tiredmenat'
'tiredmenat' anagrammed gives 'TERMINATED'.
(Other definitions for terminated that I've seen before include "done something with extreme prejudice" , "Ended" , "Stopped" , "reached the end of the line" , "Finished" .)
