The Louisiana Association of Educators says it also will file a lawsuit to throw out a set of education changes that Gov. Bobby Jindal pushed and state lawmakers passed.
Directors of the teachers' union also have endorsed an effort to recall Jindal.
The union voted Saturday to sue over changes to the state's elementary and secondary school funding formula that will pay for a statewide voucher program, online schools, college tuition scholarships and an expansion of charter schools.
The affiliate of the National Education Association claims the changes violate the Louisiana Constitution and illegally transfer local tax money from one district to another.
The union is not challenging Act 1, which changes teacher tenure, hiring and firing practices and gives superintendents more authority.
The Louisiana Federation of Teachers filed two lawsuits Thursday in East Baton Rouge District Court claiming the changes violate constitutional provisions on the passage of legislation and governing the school financing formula. That union also challenged the changes to teacher tenure, hiring and firing.
Organizers of the recall effort, which was kicked off by Calcasieu teachers Angie Bonvillain and Brenda Romero, say they're seeking endorsements from the Louisiana Federation of Teachers and the state AFL-CIO.
