In Schlieren, Zurich, two secondary classes have cycled through 14 different teachers since the summer break, raising concerns about continuity and stability in education. Experts indicate that while substitutions can be beneficial when well-planned, they often serve as a temporary solution, negatively impacting student relationships and learning quality. The challenge in finding consistent educators has been exacerbated by a teacher shortage, leading to increased uncertainty among students, particularly younger ones, who require stable relationships for effective learning.
