Gaffer in favour of getting a title back (7)
I believe the answer is:
foreman
'gaffer' is the definition.
(I know that gaffer can be written as foreman)
'in favour of getting a title back' is the wordplay.
'in favour of' becomes 'for' (being for a particular cause).
'getting' says to put letters next to each other.
'a title' becomes 'name' (I've seen this before).
'back' shows that the letters should be reversed in order.
'name' back-to-front is 'eman'.
'for'+'eman'='FOREMAN'
(Other definitions for foreman that I've seen before include "Male supervisor" , "Gaffer, boss" , "Supervising worker" , "Gaffer, overseer" , "Charge hand" .)
