Stop working after a row (4,2,4,4)

I believe the answer is:

rest on ones oars

'stop working after a row' is the definition.
(after rowing with oars)

This is the entire clue.

(Other definitions for rest on ones oars that I've seen before include "bringing a row to an end?" , "One might after a row" , "Cease working" , "Relax" , "Stop rowing" .)

I've seen this clue in The Telegraph.
