Overburden reporters with work (7)
I believe the answer is:
oppress
'overburden' is the definition.
(thesaurus)
'reporters with work' is the wordplay.
'reporters' becomes 'press' (members of the press).
'with' is a charade indicator (letters next to each other).
'work' becomes 'op' (common abbreviation for 'opus').
'press' after 'op' is 'OPPRESS'.
(Other definitions for oppress that I've seen before include "Bear down heavily upon" , "Vitality" , "Weigh down with cares, be cruel" , "Treat tyrannically" , "Subjugate by force" .)
