Staff, employees (9)
I believe the answer is:
personnel
I believe this clue is a double definition.
'staff' is the first definition.
(I've seen this before)
'employees' is the second definition.
(I've seen this before)
(Other definitions for personnel that I've seen before include "Staff complement of an organisation" , "An organisation's people" , "Members of staff" , "Crew" , "Employees collectively" .)
