Two Massachusetts high school teachers are facing disciplinary action and possibly the loss of their jobs for holding a silent antiwar protest during a school gathering. The teachers, Marybeth Verani and Adeline Koscher of Dennis-Yarmouth Regional High School, held up a sign reading “End War” during a ceremony for seniors about to enter the military. The teachers say they wanted to express their opposition because they view the ceremony as a military recruiting tool. The school has received dozens of phone calls urging administrators to fire the teachers. The teachers have been put on paid leave until further action is taken.
