Suffering can start to generate work (8)
I believe the answer is:
painting
'work' is the definition.
(I know that painting is a type of labor)
'suffering can start to generate' is the wordplay.
'suffering' becomes 'pain' (suffering is pain).
'can' becomes 'tin' (both are metal containers).
'start to' indicates taking the first letters.
The initial letter of 'generate' is 'g'.
'pain'+'tin'+'g'='PAINTING'
(Other definitions for painting that I've seen before include "Artwork" , "picture" , "Work of a kind" , "Work of art" , "Artistic work" .)
