Jo Brand's occupation? (3)
I believe the answer is:
job
'occupation?' is the definition.
(job is a kind of occupation)
'jo brand's' is the wordplay.
'brand's' becomes 'b' (this could be a standard abbreviation which I don't know about).
'jo'+'b'='JOB'
Can you help me to learn more?
(Other definitions for job that I've seen before include "Task; paid position" , "Post" , "Book; task" , "Assignment" , "Line" .)
