GALESBURG, Ill. — A teachers strike in Galesburg will affect extracurricular activities, including sports practices.

That's according to a notice Wednesday on the District 205 website, which also includes a statement from district officials.

Superintendent Bart Arthur and school board President Michael Panther say the offer teachers rejected amounts to a 5.04 percent increase over the next three years. They say that's fair "given the economic situation in Galesburg and in our state and nation."

The Galesburg Education Association turned down a contract offer late Tuesday after more than 15 hours of mediation over two days. Teachers started picketing Wednesday morning. It's the first strike in Galesburg in 37 years.

School was scheduled to start Thursday. The union criticizes the school board for waiting until "the last minute" to resolve issues.
