For a long time, the Swedish government has tried different reforms to counteract declining student results. One action was to implement a salary-lift for teachers perceived as especially skilled. However, changes within socially complex systems tend to create tensions and resistance among the staff. In this reform, a majority of teachers were excluded from the payroll raise, which led to a renegotiation of roles, rules and commitments within the faculty. In this study, the principals’ perception of the teachers’ initial reactions and responses to the implementation is the focus. The data for this study contain four narratives from principals who implemented the salary lift within their organizations. The analysis shows that the reform challenged the principals as heads of the organizations. They stated that the salary lift created conflicts and insecurities among the teachers related to their motivation, sense of trust and self-efficacy. These conflicts and insecurities seemed to fuel a spiral of mistrust within the schools in the wake of the reform.
