Lure for employee, not permanent, ahead of time (5)
I believe the answer is:
tempt
'lure' is the definition.
(I know that lure can be written as tempt)
'employee not permanent ahead of time' is the wordplay.
'employee' becomes 'temp' (I've seen this before).
'not permanent ahead of time' becomes 't' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'temp'+'t'='TEMPT'
'for' is the link.
Can you help me to learn more?
(Other definitions for tempt that I've seen before include "Attract, charm, entice" , "Entice; risk provoking (fate)" , "Entice - give rise to desire" , "Whet the appetite" , "Try to seduce" .)
