The head of Oklahoma’s largest teacher’s union says Monday’s walkout will last at least one more day. Thousands of Oklahoma public school teachers rallied at the state capital Monday to press their demands for lawmakers to approve more funding for pay raises and classrooms. So far, Hugo and Latta Public Schools, have confirmed they will remain closed today. Monday’s demonstrations come just days after Oklahoma Gov. Mary Fallin signed legislation increasing taxes on cigarettes, fuel and oil and gas production to provide teachers with raises of 15 to 18 percent.
