Do the wrong thing as well by getting a job (6)
I believe the answer is:
errand
'a job' is the definition.
(thesaurus)
'do the wrong thing as well by' is the wordplay.
'do the wrong thing' becomes 'err' (I've seen this in another clue).
'as well' becomes 'and' (I've seen this in other clues).
'by' is a charade indicator (letters next to each other).
'err'+'and'='ERRAND'
'getting' is the link.
(Other definitions for errand that I've seen before include "Short trip with a mission" , "Short journey to get or bring" , "Journey to deliver message etc" , "Messenger's job" , "Short trip to perform required task" .)
