Request time off from job (3)
I believe the answer is:
ask
'request' is the definition.
(to ask is to request something)
'time off from job' is the wordplay.
'time' becomes 't' (abbreviation).
'off from' suggests deleting specific letters.
'job' becomes 'task' (synonyms).
'task' with 't' taken out is 'ASK'.
(Other definitions for ask that I've seen before include "Something demanded" , "Make enquiry" , "Issue invitations" , "Seek an answer" , "Request, invite" .)
