On Monday, D.C. Mayor Muriel Bowser and other city leaders visited KIPP DC Promise Academy in Southeast to observe the start of the new school year.

City Administrator Kevin Donahue said that since May 1, the Department of General Services had taken care of thousands of work orders, checking off 80% of the issues identified by the end of the previous school year. However, the Washington Teachers Union President Jacqueline Pogue Lyons argued that city leaders had ignored safety recommendations made at a time when teachers are feeling less and less safe at work.

A survey conducted by the union found that 42% of D.C. teachers feel they’ve seen workplace violence increase a lot over the past year, while another 23% say it increased a little. Bowser and her top deputies have pressed the council to put school resource officers back in the classroom, while touting other programs aimed at reducing violence that impacts students.
