I know many that have left the field.
My wife views it as a vocation, a calling. She is fighting for what she believes in.
It will wear her down. One day, she will say “I’m done” and walk away. Most of her fellow teachers do it for the three months off.
The teachers I know do it for the 180 days of work per year, as well as the lack of performance metrics/accountability, the 8:30 to 3:00 workday (which includes a lunch break as well), the high pay for just passing time (automatic increases despite horrible results), the employment for life guaranteed by tenure, and the retirement benefits that are only a dream for the working stiffs that pay them.
