The workforce; the staff (8)
I believe the answer is:
manpower
This clue is a double definition.
'the workforce' is the first definition.
(I've seen this before)
'the staff' is the second definition.
(manpower can mean staff resources)
(Other definitions for manpower that I've seen before include "Workforce" , "labour force" , "Work effort" , "Staff resources" , "People available for work" .)
