Please unmask the teachers. The children need to see our faces to learn and understand language. Students need to be able to see facial expressions and smiles to feel safe and welcome at school. Teacher should have a choice. Because of the mask, many of us are now under the care of dermatologist and have sore throats after teaching all day through the mask. (7 hours a day) As a librarian, I read to 6 classes a day, and literally feel breathless and exhausted which is causing headaches. Please give us a choice  We’ve been on the front lines face to face in my county from the beginning. If an 18 year old senior can choose why can’t a teacher?
