Ye and his Donda Academy are being sued by two Black women who say they were fired from teaching positions at the school for two reasons -- retaliation for sounding the alarm on alleged education, health and safety code violations -- and for their race.

According to the lawsuit, obtained by TMZ, the women say they were the only Black teachers employed by Donda Academy when they were hired full-time earlier this year ... and they say it didn't take long for them to notice numerous health and safety violations, unlawful educational practices and extremely unusual rules at Kanye's school.

Among the alleged issues ... the women say the only lunch option available for students is sushi, every single day, and students are not allowed to bring any outside food or drink, except for water. The suit claims Kanye spends $10,000 a week on sushi.

What's more, the teachers claim Kanye did not allow crossword puzzles or coloring sheets at Donda Academy, classes could not take place on the second floor because Kanye is "afraid of stairs," and Ye didn't want children using forks or utensils.

The suit alleges Kanye did not allow artwork to be hung on walls, and no one was allowed to wear jewelry ... simply because he "did not like jewelry."

The teachers even claim Kanye didn't allow chairs, forcing children to sit on foam cushions or stand, while teachers were relegated to standing or using a stool.

Donda Academy, the suit says, required everyone to wear all black from head-to-toe ... and Nike and Adidas brands were forbidden.

The teachers claim the school doors were physically locked from the outside during the school day, and students weren't allowed to go outside until they went home ... with the entire school, pre-kindergarten through 12th grade, taking lunch and recess at the same time indoors.

The suit claims Donda Academy didn't have a janitor or a school nurse ... and there were no trashcans outside classrooms or in the kitchen. Meanwhile, they say student medications were stored in a closet with other expired medications just scattered around unsecured.

And, get this ... the teachers claim there are no lesson plans or proper disciplinary procedures in place, resulting in students going undisciplined for multiple instances of bullying and physical assaults against peers and teachers.

The teachers claim when they tried to run the alleged issues up the flagpole, they were threatened not to reach out to Kanye.

The women say they were ultimately fired ... and they're blaming their termination on retaliation and racial discrimination. They also claim their paychecks were often short up to $2,700 per pay period ... so they're suing Kanye and Donda Academy for money.

We reached out to Kanye's camp ... so far no word back.
