Governor Bill Lee signs a law that will allow retired teachers in Tennessee to go back to the classrooms while keeping their retirement benefits.

The legislation was created to help fill teacher vacancies across the state.

The Professional Educators of Tennessee says there are likely 2,000 teacher job openings in the state. There are 128 teacher vacancies in the Knox County Schools system.

The new law will allow teachers to keep benefits but they can only sign a one-year contract. Retired teachers can resign each year until the law ends in 2025. These teachers can either fill full-time or substitute positions. The new law also benefits retired school bus drivers to help fill some of their vacancies.
