The leading mayoral candidate, who has a 5-year-old son in a Manhattan public school, took aim at the city’s 190,000-member United Federation of Teachers for its perceived role in delaying school openings during an interview with POLITICO this week.

“I will confess to being a parent that has been frustrated by how slow our schools have been to open, and I do believe that the UFT has been a significant reason why our schools have been slow to open,” Yang said…

“The UFT was the leading force in New York City public schools opening and opening safely, protecting students and staff. Mr. Yang needs to do his homework,” UFT president Michael Mulgrew said in a prepared statement. The union leader has blamed the de Blasio administration for problems associated with school reopenings, which are underway with relatively few virus occurrences.
