D.C. Public Schools (DCPS) and the union have sparred for months over plans to reopen schools and reached an agreement in December.
The union asked an arbitrator to review possible violations of the agreement by DCPS that were found to be largely unproven over the weekend.
The arbitrator did find that two schools should not reopen until coronavirus safety issues are resolved and building walkthroughs are conducted.
“The WTU, however, believes there are other safety violations of its memorandum of agreement with DCPS and unhealthy conditions at multiple schools. The WTU is asking for additional school-by-school walkthroughs … conducted with WTU, mayoral and DCPS staff,” the statement says.
