Hospital workers (9)
I believe the answer is:
orderlies
'hospital workers' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for orderlies that I've seen before include "Hospital attendants or soldiers working for officers" , "Hospital workers" , "Solderer I join as soldiers who do errands for officers" , "Soldiers attending superior officers" , "Military or hospital attendants" .)
