Tasks suited jerks (6)
I believe the answer is:
duties
'tasks' is the definition.
(I've seen this before)
'suited jerks' is the wordplay.
'jerks' indicates an anagram (I've seen 'jerk' mean this).
'suited' is an anagram of 'DUTIES'.
(Other definitions for duties that I've seen before include "Tasks or tariffs" , "Assignments, chores" , "Tasks to be done" , "Obligations or functions" , "Obligations or taxes" .)
