Persuaded a casual worker to make hay (7)
I believe the answer is:
tempted
'persuaded' is the definition.
(tempting is a kind of persuading)
'a casual worker to make hay' is the wordplay.
'a casual worker' becomes 'temp' (I've seen this before).
'to make hay' becomes 'ted' (I've seen this before).
'temp'+'ted'='TEMPTED'
(Other definitions for tempted that I've seen before include "Drawn to" , "wooed" , "Invited" , "Enticed" , "Tried to seduce" .)
