After a break, creative work will resume (7)
I believe the answer is:
restart
'resume' is the definition.
(I know that resume can be written as restart)
'after a break creative work' is the wordplay.
'after' says to put letters next to each other.
'a break' becomes 'rest' (a rest is taking a break).
'creative work' becomes 'art' (artwork).
'rest' put next to 'art' is 'RESTART'.
'will' acts as a link.
(Other definitions for restart that I've seen before include "launch again" , "Resume" , "Commence again" , "Jumping the gun will mean" , "begin afresh" .)
