Job centre welcoming husband (5)
I believe the answer is:
chore
'job' is the definition.
('chore' can be a synonym of 'job')
'centre welcoming husband' is the wordplay.
'centre' becomes 'core' (core is a kind of centre).
'welcoming' is an insertion indicator (in sense of 'inviting in').
'husband' becomes 'h'.
'core' going around 'h' is 'CHORE'.
(Other definitions for chore that I've seen before include "Mundane task" , "Unpleasant task" , "unwelcome task" , "Manipulate; name" , "Boring task" .)
