A strain, perhaps, for the working man (7)
I believe the answer is:
artisan
'the working man' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'a strain perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'strain' with letters rearranged gives 'rtisan'.
'a'+'rtisan'='ARTISAN'
'for' is the link.
Can you help me to learn more?
(Other definitions for artisan that I've seen before include "Tsarina (anag.)" , "Train as (anag) - craftsman" , "Technician" , "Mechanic" , "Crafty sort" .)
