TUESDAY UPDATE: About 200 people were at the Monday rally. The city's teachers union approved a $10,000 donation to the Chicago teachers' strike fund. GothamSchools says the UFT isn't likely to follow Chicago's lead, but you can check out their upcoming explanation of why the strike still matters for our city.

MONDAY: Some New York City teachers are rallying to support the Chicago teachers who were on the picket lines Monday morning. Chicago's Democratic Mayor Rham Emanuel says the city has made a generous offer that would raise teachers' salaries. But leaders of the reform-led Chicago Teachers Union say the strike is not just about money -- they want improvements made to Chicago's schools, including smaller class sizes, and a nurse and a social worker in every school. They also note that the proposed raises would be offset by a hike in health care costs.

If you're with the Chicago teachers, you can join NYC teachers and Occupy Wall Street at Union Square at 5pm.

NYC connection: Chicago schools superintendent J.C. Brizard was a teacher and principal of Westinghouse High School before going to the high school division at Tweed. He left to become head of schools in Rochester, NY and then was off to Chicago.
