Do Teacher Strikes Harm Educational Attainment of Students?

This paper investigates the effects of a teacher strike on student achievement. From May 1990 until November 1990 teachers in the French community of Belgium stroked to obtain a salary increase. We exploit the political division of Belgium in a French community and a Flemish community, with similar educational institutions, for estimating the long-term effects of the strikes. Based on a difference-in-differences approach, using data from two different surveys, we find some evidence that the strikes reduced educational attainment and increased class repetition. We also find that the strikes led to a significant reallocation of students to a lower level of higher education. Overall, the results suggest that teacher strikes can lead to substantial costs for those not involved in the conflict.
