SEATTLE (AP) – Teachers in Seattle have overwhelmingly voted to authorize a strike as contract talks continue on the eve of the new school year.

Seattle Education Association President Jennifer Matter announced Tuesday that 95% of ballots returned by the union’s membership favored going on strike absent an agreement with Seattle Public Schools.

Issues include pay, staffing ratios for special education and multilingual students, and student mental health support.

School is due to start Wednesday but the district has warned parents a delay is likely.

Districts across the country have been dealing with fallout from the pandemic, including strains on the mental health of teachers and students, as well as limited resources for meeting teacher demands.
