World number one Aryna Sabalenka says tennis authorities "follow their interests" with regards to the tennis calendar and are not "focusing on protecting all of us".
Players have been raising concerns about the schedule in recent months, saying it is too long and intense.
Leading players on the women's tour are expected to play at least 20 mandatory events - four Grand Slams, 10 WTA 1000s and six 500s.
Belarusian Sabalenka said she would skip some events this year to protect her body.
"The season is definitely insane, and you see so many players getting injured," Sabalenka said after her 6-3 6-3 victory over Sorana Cirstea at the Brisbane International.
