Working men due to embrace scheme for the workless (10)
I believe the answer is:
unemployed
'the workless' is the definition.
(thesaurus)
'working men due to embrace scheme' is the wordplay.
'working' indicates an anagram.
'to embrace' is an insertion indicator.
'scheme' becomes 'ploy' (I've seen this in another clue).
'men'+'due'='mendue'
'mendue' with letters rearranged gives 'unemed'.
'unemed' going around 'ploy' is 'UNEMPLOYED'.
'for' is the link.
(Other definitions for unemployed that I've seen before include "Idle" , "out of position?" , "Out of work" .)
