Support the workforce (5)
I believe the answer is:
staff
I believe this clue is a double definition.
'support' is the first definition.
(thesaurus)
'the workforce' is the second definition.
(I've seen this before)
(Other definitions for staff that I've seen before include "five lines?" , "Rod of authority" , "teachers employed in school" , "Rod; workers" , "men?" .)
