Man -- name sure confused hospital worker (5,5)
I believe the answer is:
staff nurse
'hospital worker' is the definition.
(I've seen this before)
'man name sure confused' is the wordplay.
'man' becomes 'staff' (both can mean to work at a particular post**).
'name' becomes 'n' (common abbreviation e.g. on forms).
'confused' indicates an anagram.
'sure' anagrammed gives 'urse'.
'staff'+'n'+'urse'='STAFF-NURSE'
(Other definitions for staff nurse that I've seen before include "sister senior to him" , "Senior healthcare professional" , "hospital worker" , "tender below top level" , "tender, helping sister" .)
