Novak Djokovic, women's world number two Ons Jabeur and six other players will form the first executive committee of the controversial Professional Tennis Players Association (PTPA).
The PTPA wants to increase the power of the players, taking it away from the current bodies - the ATP and WTA.
Co-founder Vasek Pospisil will also be on the first executive committee.
The Canadian will be joined by Hubert Hurkacz and Paula Badosa, both ranked 11th in the respective rankings, Americans John Isner and Bethanie Mattek-Sands, plus China's Zheng Saisai.
Djokovic, a winner of 21 Grand Slam titles and one of the sport's biggest names, resigned as president of the ATP player council to front the PTPA, an organisation which was criticised for originally only including male players.
