Introducing dodgy equipment at first to working nurses shows disrespect (8)
I believe the answer is:
rudeness
'disrespect' is the definition.
(thesaurus)
'introducing dodgy equipment at first to working nurses' is the wordplay.
'introducing' means one lot of letters goes inside another (some letters introduced or inserted into others).
'at first' says to take the initial letters.
'to working' is an anagram indicator.
The first letters of 'dodgy equipment' is 'de'.
'nurses' is an anagram of 'runess'.
'de' put into 'runess' is 'RUDENESS'.
'shows' acts as a link.
(Other definitions for rudeness that I've seen before include "Incivility" , "Bad manners, lack of politeness" , "Lack of courtesy or manners" , "Offensive bad manners" , "Lip" .)
