Schools sticking with in-person learning scramble for subs

Principals, superintendents and counselors are filling in as substitutes in classrooms as the surge in coronavirus infections further strains schools that already had been struggling with staffing shortages. In Cincinnati, dozens of employees from the central office were dispatched this week to schools that were at risk of having to close because of low staffing. The superintendent of Boston schools, Brenda Cassellius, tweeted she was filling in for a fifth grade teacher. San Francisco’s superintendent, Vince Matthews, has called on all employees with teaching credentials to take a class.
