(CNN) A school district outside Buffalo, New York, has delayed the start of online-only learning programs for grades 5-12 because of mass staff resignations and leaves of absence, the superintendent announced on Friday. In a letter to families, Williamsville Central School District Superintendent Scott Martzloff said 90 staff members have taken a leave of absence due to Covid-19 and 111 staff members resigned. Additionally, 2,361 students opted into online-only learning, including 1,375 middle and high school students, creating more than 80 virtual teacher vacancies, the letter reads. Due to the reduction in staffing, school will be delayed until further notice for all students grades 5 through 12 in the online-only learning model, Martzloff said. Once adequate staffing arrangements are made, the district will notify families of a new start date, Martzloff said in a video posted online.
