The Chicago Teachers Union is planning a one-day walkout on April 1.
CTU's House of Delegates will reportedly consider approval of the walkout next week.
"We will not go to work on April 1. We will close the schools on April 1," CTU Vice President Jesse Sharkey told the Chicago Tribune. "What we would hope is that the public joins us and that we see this as a one-day action to fight for school funding."
"We're saying that we're arguing for picket lines going up at schools on April 1," Sharkey added, "and that school would not be in session that day."
The district and CTU have different legal theories on whether teachers can hit the picket lines on April 1.
The Chicago Public Schools provided a statement about the CTU's planned demonstration:
Regardless of CTU's actions, April 1 is a school day, and we expect teachers to be in classrooms teaching and students to be in classrooms learning. Our students get one chance at an education and we will continue to negotiate in good faith with CTU. We will also stay in communication with parents.
With respect to legal action, CPS continues to look at our options. There is no question that a one-day strike before fact-finding concludes is not only illegal, but also not in the best interest of our children.
After CPS officials announced earlier this month the implementation of three furlough days this school year as a means to help tackle the cash-strapped school district's budget problems, CTU vowed to hold an "unfair labor practice day of action" against the district's "austerity agenda" on April 1. The union specified this week that it would call for members to walk off the job on that day.
CTU's announcement comes amid ongoing contract negotiations between the union and school district.
