Summary
Even though the academic press recognizes generational diversity and its consequences, the related findings are fractured, and research is incomplete regarding methodology and theoretical background. In adopting a social identity perspective concerning groups and self‐conception, we argue that the social identity perspective is in line with generational identity theory. Employing a cognitive mapping method (repertory grid technique, mixed methods), the present study taps into three generations (Baby Boomers, Generation X, and Generation Y) of Belgian managers' minds and demonstrates how they perceive their own and the two other generations. Our research reveals that perceptions of their own and other generations may direct social categorization and generational stereotypes of the in‐group and out‐group(s), that some of these stereotypes can be enacted, and that generational stereotypes do not necessarily coincide with age‐based stereotypes. Several metapatterns in the stereotypes are revealed as well. Hence, we contribute to the emerging field of research that calls for an identity‐based approach rather than a cohort‐based approach to generations and that validates the argument that generations as a workplace phenomenon must be considered a legitimate phenomenon. Insights into generations as social categories give a richer view of the interrelationships between generations in multigenerational situations at work.
