The players' union also announced that their message is only part of a series of questions that they want to solve before the season can start.
Among other things, the league has announced that the players may need to lower their salaries in the coming seasons to even out the financial losses.
The NBA has previously said that they want to start on December 22 to be able to play the classic Christmas matches and reach the playoffs before the Olympics in Tokyo 2021.
It is planned to start the league without an audience.
