Area teachers are setting a bad example for our children by skipping class. So many Madison teachers called in ?sick? for work that school officials canceled classes for a third straight day Friday…Those teachers who have ditched on their classes for one, two or in the case of the Madison district, three days should learn from another educator: UW-Madison Chancellor Biddy Martin.

Martin wrote on her Twitter account Wednesday night: The ?political process is very important, but this should not come at the cost of instruction.
