我在学校教书，一个黑人老师说他就曾经被白人员工（不知道他是老师）让他去清理垃圾，这个黑人老师觉得很受伤

刚看到这学校新加了一门必修课：Last year, our Instructional Council (IC) voted unanimously to adopt a Diversity and Social Justice (DSJ) requirement for all degrees and certificate of proficiency programs—the first significant change in instructional degrese requirements in over two decades.
