Concerns about safety of schools across the city have teachers in the Bronx rallying, calling their school at the Grace Doge Campus unsafe.

School staff returned to the building on Tuesday and since then, teachers and advocates say they have a growing list of concerns when it comes to opening the school doors.

Every morning since, teachers and sometimes parents rally outside the school, hoping that their voices will spark a change.

Educators say back in March the building became a COVID-19 cluster after a teacher at Crotona International High School located within the Grace Doge Campus tested positive for COVID-19.

Now, with schools slated to reopen to students at the end of the month, campus instructors say proper ventilation must be in place in spaces like the cafeteria, which they feel it is lacking.

News 12 is told they've written letters to the president of UFT and other elected officials, going so far as to confronting a UFT representative who inspected their campus Tuesday right before teachers were set to report inside.
