Seven families across the state have filed a lawsuit challenging teacher tenure laws.
Parents and teachers rallied on the steps of City Hall Monday morning.
They say the law keeps ineffective and even dangerous teachers in the classroom.
The suit also claims the tenure law violates the state constitution's guarantee of a sound basic education to all students.
Student advocate Campbell Brown is promising to provide the families with financial support, but knows it's going to be a tough fight.
"I'm so inspired by what these people are doing. This is not going to be easy and they are so incredibly brave to be taking this on and I'm so proud to be standing here and supporting them today," Brown said.
United Federation of Teachers President Michael Mulgrew responded by saying quote, “Campbell Brown may be tearing up, but her secret hedge-fund supporters will be crying all the way to the bank if she succeeds in her mission to undercut public education and privatize our schools. Parents know that attacking teachers is not the answer to the problems of New York’s public schools. We expect New York’s courts to reject the fact-challenged and legally questionable assertions in this case.”
