County provides employees (6)
I believe the answer is:
staffs
This clue is a triple definition!
'county' is the first definition.
(Staffordshire)
'provides' is the second definition.
(staffing is a kind of providing)
'employees' is the third definition.
(I've seen this before)
(Other definitions for staffs that I've seen before include "All counties' players" , "English county (abbr)" , "County; provides with workers" , "Nineteenth century artist" , "Where Tamworth is" .)
