A former teacher at Sherman Middle School in Madison says she left because of the principal.  Writing in a blog, the teacher contends Principal Kristin Foreman’s approach leads to unruly students and over-worked teachers.  One parent confirms the allegations, telling W-I-S-C News-3 she has often seen teachers crying and speaking in whispers.  Parent Heather Banschbach says there is obvious frustration and she saw it so frequently it can’t just be attributed to a bad day.  The Madison Metropolitan School District pushed back in a statement against the “personal, public shaming” one of its principals.
