Teachers in the Illini Bluffs School District in central Illinois are striking over a new drug-testing policy that administrators want to add to a new contract.

The district in Glasford was scheduled to start classes on Aug. 17. But teachers don't want to submit to random drug and alcohol testing. Glasford is 15 miles southwest of Peoria.

District attorney Karl Meurlot says most of the 63 teachers are on strike. The district is interviewing potential replacements and could start classes with them next week.

At a rally Tuesday about 300 people, like 16-year-old high school student Kyle Sweet, supported the teachers. He says he's never suspected any of his teachers had a drug problem.

The district's other employees already take drug tests.
