Students will make the switch Friday and will continue to take classes remotely until Nov. 1. The district says a high number of staff absences and a lack of substitutes at the middle school prompted the need for remote instruction. The switch follows a notification from the Broome County Health Department that two COVID-19 cases were confirmed at the middle school and the Ann G. McGuinness Elementary School. ENDICOTT (WBNG) — The Union-Endicott School District says students at Jennie F. Snapp Middle School will switch to remote instruction for two weeks. There are no impacts to the Ann G. McGuinness Elementray School as of Oct. 22.
