Randi Weingarten, United Federation of Teachers president, is using the reading rugs in city classrooms as a latest issue to be used in teachers' contract negotiations with the city. The union says reading rugs used in pre-K till second grade are "havens for skin flakes, insect parts, rodent droppings and other unhealthy gunk." Though this information is based on only nine schools (which do not have vacuums or custodians who will vacuum), Gothamist still says, "EW EW EW." It's bad enough for adults to be living in hovels, strewn with pizza boxes and beer bottles, there is no reason for children to be experiencing squalor so early on while hearing the story of Pee Wee, the hamster who lives in Central Park.
