Oklahoma state law technically forbids public school teachers from even threatening a strike, which seems contradictory considering Oklahoma’s state motto means “labor conquers all things.” In April 1990, however, a four-day walkout resulted in an education reform bill, which included long-sought raises.

KTUL reported on Sunday night that teachers are expected to set and announce a date for the strike next week. Reed told the Tulsa World that the date currently under consideration is April 2, when the state’s standardized testing begins, because that’s “when it might hurt the most.”
