Club for the workers (5)
I believe the answer is:
staff
I believe this is a double definition.
'club' is the first definition.
(thesaurus)
'workers' is the second definition.
(members of staff)
'for the' acts as a link.
(Other definitions for staff that I've seen before include "Rules needed for scoring" , "Employees; weapon" , "teachers employed in school" , "Administrators etc - stick" , "Stick - office employees" .)
