Cry when shut out of the job centre (5)
I believe the answer is:
shout
'cry' is the definition.
('shout' can be a synonym of 'cry')
'shut out of the job centre' is the wordplay.
'out of' means one lot of letters goes inside another.
'centre' indicates the central letters.
The centre of 'job' is 'o'.
'shut' going around 'o' is 'SHOUT'.
'when' acts as a link.
(Other definitions for shout that I've seen before include "Yell" , "bellow" , "Utter a loud cry" , "(Statement) with opposite sense intended" , "Call loudly" .)
