Emancipated worker's carte blanche (4,4)
I believe the answer is:
free hand
'carte blanche' is the definition.
(I've seen this before)
'emancipated worker's' is the wordplay.
'emancipated' becomes 'free' (similar in meaning).
'worker' becomes 'hand' (hand is a kind of worker).
'free'+'hand'='FREE-HAND'
(Other definitions for free hand that I've seen before include "Drawn without aids" , "Right to act completely at one's own discretion" , "Authority" , "Done without mechanical aid or device" , "Style of drawing - carte blanche (8;4,4)" .)
