I respect tenure as a valuable tool to protect teachers.
Howeer, as it currently plays out in school districts across the country, teacher tenure often creates a "last hired, first fired" policy when budgets are tightened.
How can we address this connundrum? Newer teachers are finding themselves starting over every year or two as they are laid off before making tenure. This impacts their salary, benefits and (naturally) ability to get tenure. And I'm sure it's an important contributing factor to the teacher retention problem.
