It’s always tough to be a public school teacher, but it is especially tough in Oklahoma—and Oklahoma teachers are ready to walk in protest.

Inspired by West Virginia’s recent strike and by their own longstanding grievances, they’ve begun using social media to organize support for a statewide walkout. On Thursday afternoon, the Oklahoma Education Association will hold a press conference with public workers to announce demands: If the state legislature doesn’t pass a pay raise and increase funding for public schools by April 1, teachers will strike on April 2. As in West Virginia, Oklahoma teachers technically do not have the right to strike; their walkout will be a work stoppage.

“Educators have not had a raise since 2008, neither have education support professionals, neither have state employees,” explained Katherine Bishop, the vice president of the Oklahoma Education Association. “State education funding has been cut more than any other state in the nation. Quite frankly, school budgets have been cut so much that teachers do not have access to the materials they need to do their jobs.”

In the Facebook groups where teachers and parents are coordinating the walkout, “West Virginia” has been a common refrain. Earlier this week, following a nine-day strike that shuttered schools across the state, teachers won a 5 percent pay bump. If they did it, the reasoning goes, so can we. Some West Virginian teachers have even joined the Oklahoma Facebook groups. There are plenty of reasons for the cross-state solidarity: Oklahoma and West Virginia teachers suffer similar structural indignities.

In some cases, Oklahoma’s public schools face unusually dire straits. Average salary for an Oklahoma public school teacher is the lowest in the country, and the state faces a severe teacher shortage. Ninety-one public school districts out of 584 have reduced the school week to four days, according to Bishop, and at some schools, teachers can only make 30 photocopies a week to provide materials to all their students. The situation is so serious that, in 2017, the Oklahoma City school system threatened to sue the state legislature for underfunding its schools. And the crisis predates 2017: Oklahoma teachers also walked out in 1990 over low pay.
