The Wissahickon School District is laying off five support staff workers as well as a school nurse classified as a temporary professional. The school board approved the furloughs Monday night. In addition, another support staff employee and school nurse were demoted. The job actions are the result of a staff realignment made necessary by the pending closure of Mattison Elementary School in Ambler. District officials say attempts were made to find jobs for the laid off employees. They also say those affected could be recalled during the next school year if a position opens for them.
