A business worry (7)

I believe the answer is:

concern

I believe this clue is a double definition.

'a business' is the first definition.
('concern' can be a synonym of 'business')

'worry' is the second definition.
('concern' can be a synonym of 'worry')

(Other definitions for concern that I've seen before include "Disquiet" , "Feeling of anxiety or sympathy" , "Cause of anxiety" , "Business organisation" , "Relate to; anxiety" .)

I've seen this clue in the Evening Standard.
