County workers in a number of offices? (6)
I believe the answer is:
staffs
I believe this is a double definition.
'county' is the first definition.
(Staffordshire)
'workers in a number of offices?' is the second definition.
(more than one group of staff)
(Other definitions for staffs that I've seen before include "Where Tamworth is" , "Sceptres, county (abbr.)" , "music bars" , "provides help for > crooks" , "Poles" .)
