Through with the job, getting leave (10)
I believe the answer is:
permission
'leave' is the definition.
(thesaurus)
'through with the job' is the wordplay.
'through' becomes 'per' (I've seen this before).
'with' says to put letters next to each other.
'the job' becomes 'mission' (I can't explain this - if you can you should believe this answer much more).
'per'+'mission'='PERMISSION'
'getting' is the link.
Can you help me to learn more?
(Other definitions for permission that I've seen before include "Visa, eg" , "Leave" , "Allowance" , "Consent, authorisation" , "Green light" .)
