Work permit breaking record, public note (4,6)
I believe the answer is:
open letter
'work permit breaking record' is the definition.
I can't judge whether this definition defines the answer.
'public note' is the wordplay.
'public' becomes 'open' (associated in meaning).
'note' becomes 'letter' (I've seen this before).
'open'+'letter'='OPEN-LETTER'
Can you help me to learn more?
(Other definitions for open letter that I've seen before include "No confidential correspondence" , "widely-publicised protest" , "Communication intended for public reading" , "public protest" , "Use knife, perhaps" .)
