Another protest was staged outside Communication and Media Arts High School in Detroit.
The fight isn't just about classroom conditions, but the suspension of dozens of students.
The school called a mandatory meeting for parents about the suspensions but there was some confusion. The kids were told the five-day suspension was reduced to just one.
But when they showed up for school Wednesday, they were turned away.
CMA principal Donya Odum ordered FOX 2 to leave the school as dozens of parents sought to get their children back in it.
"You can't be in the building," Odum said.
Administrators suspended more than 80 students for walking out of class Monday. The students sought to stand in solidarity with teachers over Detroit Public Schools.
"Since the teachers didn't walk out on their own, we had to speak for them," said student Antonio Willis.
And protest subpar building conditions.
"I think the students had to do this to prove a point," said parent Roselyn Coe. "My daughter has been telling me she can't use the bathrooms because they aren't suitable to use. She's cold and has to keep her coat on most of the time in the classroom."
The students were initially given five-day suspensions but they were later reduced to just one day.
Many protested again after being turned away when they tried to return to school Wednesday morning.
The good news from this meeting--the suspensions won't go on their records, while some students believe they should not have been suspended to begin with.
"Her reasoning was, when we walked out, it was affecting attendance," said student Judy Russell Pearce. "I personally don't feel it was an attendance policy being effected, I think it was her trying to keep her image."
But now are parents are the ones making some noise. Many are questioning if the principal is doing enough to address students' concerns.
"She gave us all politically correct answers, that was what I summed it up to," said one parent. "The kids have a point that something is wrong inside the building, something is wrong with the system and it needs to be fixed."
"This is not the last time you are going to hear about CMA on the news," Willis said.
The Detroit Federation of Teachers is planning a major announcement set for Thursday afternoon. No word yet on what news they plan to break.
