No going back with article by patient man at work (2,3,3)
I believe the answer is:
on the job
'at work' is the definition.
(thesaurus)
'no going back with article by patient man' is the wordplay.
'going back' shows that the letters should be reversed in order.
'with' means one lot of letters go next to another.
'article' becomes 'the' (the 'definite article' part of speech**).
'by' is a charade indicator (letters next to each other).
'patient man' becomes 'job' (biblical character famous for patience).
'no' backwards is 'on'.
'on'+'the'+'job'='ON THE JOB'
(Other definitions for on the job that I've seen before include "At work" , "(Of training) done while working" , "Informally working, being busy" , "Bonking" .)
