That's why we wound up with a 60 game season this year. Players wanted 80. Owners were able to stall as long as possible until there was only time for 60.
They will do as much as they can to minimize the number of games in front of no fans or extremely diminished fans next year. The only thing fighting in the other direction will be the players union, who of course wants to play more games (or, more accuratenly, wants to get paid for more games).
