Put back on the duty list in turns (7)
I believe the answer is:
rotates
'turns' is the definition.
(rotating is a kind of turning)
'put back on the duty list' is the wordplay.
'put' becomes 'set' (setting is a kind of putting).
'back' is a reversal indicator.
'on' means one lot of letters go next to another.
'the duty list' becomes 'rota' (I've seen this before).
'set' reversed gives 'tes'.
'tes' after 'rota' is 'ROTATES'.
'in' is the link.
(Other definitions for rotates that I've seen before include "Takes turns" , "Spins round" , "Turns around an axis" , "revolves" , "Goes round" .)
