Stagnating teacher salaries and the widening gap between public school teachers and similar workers have led to growing concerns that teachers will seek out additional employment—possibly impacting their instructional practice in the process. Using data from the Schools and Staffing Survey and the National Teacher and Principal Survey from 1994–2021, we show that teacher multiple jobholding has been remarkably stable over time. When examining the predictors of multiple jobholding, we find a high degree of variation across the timing, focus, and setting of teachers’ additional work. Using regression analysis, we show that teachers who work an additional job have lower turnover rates, with the exception of teachers who work outside of school, who leave teaching at higher rates.
