PurposeUnderpinned by Social Cognitive Theory (SCT), this study aimed to examine the mediating role of employees' adaptability in the relationship between the five managerial climate factors (i.e., trust, supportiveness, openness, clarity of goals and participative) and change readiness in public sector organisations.Design/methodology/approachAdopting the quantitative approach, data were collected from 379 administrative and diplomatic officers. Analysis was done using partial least squares structural equation modelling (PLS-SEM).FindingsThe results showed that trust and clarity of goals are significant motivational factors that accelerate employees' adaptability. Adaptability, in turn, was found to mediate the effect of trust and clarity of goals on employees' change readiness.Originality/valueThis study contributes to theory and practice by examining employees' adaptability as an intervening variable in the relationship between managerial climate factors and change readiness with specific reference to the public administration context.
