PurposeThe paper aims to clarify how work-specific characteristics at both the individual and organizational level influence professional civil servants’ readiness for change during the implementation of reforms in public administration. We examine the influence of work characteristics at the individual and organizational levels, such as reform-related strains, organizational climate, and organizational professionalism, on the employees’ response to change. In addition, we also consider the interaction between these specific work characteristics.Design/methodology/approachThis article employs a quantitative multi-level analysis to examine the influence of individual and collective predictors of employees' readiness for change. For our analysis, we used data from the evaluation of a school reform in Switzerland aimed at aligning teachers' working conditions with those of other administrative employees. The survey conducted for the evaluation includes responses from 2,162 teachers.FindingsOur study expands the understanding in public management research of work characteristics that either promote or reduce employees’ readiness for change in the public sector. Our findings suggest that the organizational level, in our case the school level, influences the individual’s response to change. Furthermore, the role of organizational professionalism in terms of a reform-related transformation of the identities, structures, and practices of the actors concerned is highlighted as a potential stressor and catalyst that reinforces the negative correlation between reform-related stress and willingness to change.Practical implicationsThis paper offers insights into how public managers can effectively overcome challenges in the implementation process of public school reforms. This also includes the awareness among change agents that positively associated changes at the organizational level may have negative consequences at the individual level, due to the fact that they affect professional understanding, for example, which may cause the affected actors to respond with resistance.Originality/valueThis paper contributes to the small number of multi-level research studies on the responses to change in public administration and answers the call for research to investigate the hurdles that may arise when implementing change. Further, the paper contributes to the literature on the impact of new public management (NPM) on the identity of professional civil servants.
