Teachers in a central Illinois school district are picketing in an effort to gain parents' support as contract negotiations stall.

According to reports, teachers in Pleasant Plains held signs Wednesday that read "Let's work together for kids" and "Make it better." The teachers have been working under an expired contract for nearly three months and negotiations over a new contract began in April. The district had 1,300 students and 88 teachers last year.

The school board president says bargaining teams haven't agreed on monetary and administrative terms. He says a $7 million construction project has strained district finances.

Teachers union leaders declined to comment on specific bargaining points but said the process has been more difficult than usual. They say members haven't held an informational demonstration since 2001.
