Hundreds resign, retire amid extremely challenging year for educators and last updated 2021-03-16 08:10:34-04 KILLEEN, TX â Thousands of teachers have resigned or retired over the last year, but what's more, is the number of educators who've died across our nation from COVID-19. As many districts continue looking at mitigating viruses in the years to come, the Killeen Educators Association highlights the challenges faculty still face. "Yes the kids might be okay, but they're not going to empty schools they're not going to empty classrooms, they're going to people who could very much well die from this virus," said Jennifer Lee, an educator with KISD.
