Does she have half a case against heartless employer? (7)
I believe the answer is:
accuser
'does she have half a' is the definition.
I can't judge whether this defines the answer.
'case against heartless employer?' is the wordplay.
'case' becomes 'acc'.
'against' says to put letters next to each other.
'heartless employer?' becomes 'user' (someone who employs or uses something. I am not sure about the 'heartless' bit.).
'acc'+'user'='ACCUSER'
(Other definitions for accuser that I've seen before include "Person charging" , "who tries to blame someone else" , "Person making a charge" , "one levelling the charges" , "One who brings a charge" .)
