Michelle Williams says women need to be listened to and fairly compensated for their work, during her Emmy-winning speech in Los Angeles.
The Brokeback Mountain actress won the award for best actress in a limited series or movie for her work in Fosse/Verdon, the eight-part FX series co-starring Sam Rockwell.
She said her win was an acknowledgement "of what is possible when a woman is trusted to discern her own needs, feel safe enough to voice them and feel respected enough to be heard".
Williams infamously received just $US1,000 ($A1,476) to reshoot scenes from 2017's All the Money in the World, while co-star Mark Wahlberg negotiated $US1.5 million ($A2.2 million) for the added scenes.
Williams has said she felt paralysed after learning of the disparity.
