Working after university partnership (5)
I believe the answer is:
union
'partnership' is the definition.
(thesaurus)
'working after university' is the wordplay.
'working' becomes 'on'.
'after' says to put letters next to each other.
'university' becomes 'uni' (I've seen this in other clues).
'on' put after 'uni' is 'UNION'.
(Other definitions for union that I've seen before include "America" , "Association with a common purpose" , "Marriage; pipe joint" , "State of being joined together" , "Amalgamation" .)
