Put down work papers (7)
I believe the answer is:
oppress
'put down' is the definition.
(thesaurus)
'work papers' is the wordplay.
'work' becomes 'op' (abbreviation for opus).
'papers' becomes 'press' (I've seen this before).
'op'+'press'='OPPRESS'
(Other definitions for oppress that I've seen before include "Subjugate or weigh on" , "Treat cruelly" , "Treat harshly" , "Be brutal to" , "Govern with cruelty and injustice" .)
