Guided by the Career Construction Theory (Savickas, 2013), our research model posits that individuals rely on their adaptability resources and implement adapting responses, in the form of ingratiation, to increase their promotability at work. In addition, the indirect relationship between career adaptability and promotability via ingratiation is further strengthened by high career sponsorship. The research model was tested and the translated Career Adapt-Abilities Scale (CAAS) Thailand form was validated using a cross-sectional survey of 265 subordinate–supervisor dyads. Results demonstrate adequate levels of internal consistency (ɑ=.96) and the factor structure corresponded with prior CAAS international validation. The moderated mediation model was supported and as expected: (a) ingratiation, as an adapting response, mediated the positive relationship between career adaptability and promotability, and (b) the mediated relationship between career adaptability and promotability via ingratiation was stronger for individuals with higher career sponsorship. Taken together, the findings support the cross-national measurement equivalence and utility of CAAS in non-Western and developing countries. More importantly, our study offers the groundwork for understanding adapting responses and the augmenting role of career-specific contextual support. •We tested the role of career adaptability and ingratiation in predicting promotability.•Ingratiation mediated the career adaptability and promotability relationship.•Career sponsorship strengthened the effects of ingratiation on promotability.•CAAS was translated and validated in Thailand.
