Michelle Hackman and Eric Morath:

Teachers and other public education employees, such as community-college faculty, school psychologists and janitors, are quitting their jobs at the fastest rate on record, government data shows.

A tight labor market with historically low unemployment has encouraged Americans in a variety of occupations to quit their jobs at elevated rates, with the expectation they can find something better. But quitting among public educators stands out because the field is one where stability is viewed as a key perk and longevity often rewarded.

The educators may be finding new jobs at other schools, or leaving education altogether: The departures come alongside protests this year in six states where teachers in some cases shut down schools over tight budgets, small raises and poor conditions.
