Increasing dynamics of careers make the development and application of different career resources important for successful career development. The study aimed to understand how different career resources are related to each other and different forms of career success, Examining 574 employees with 3-waves of 1-month time lags, we assessed relations between key resources (i.e., self-esteem and optimism), career adaptability resources (i.e., concern, control, curiosity, confidence), and knowledge/skills, motivational, and environmental career resources and their predictive utility for different forms of subjective and objective career success (i.e., salary). Results showed that career adaptability resources are highly related to other types of career resources, but career adaptability and other career resources each explain unique variance in different facets of career success. Using relative weight analyses, we found that especially motivational and environmental career resources are meaningfully positively related to different facets of subjective career success, whereas knowledge and skills career resources are most prominently positively related to objective career success. Under consideration of other career resources, career adaptability related negatively to salary. The findings contribute to career construction theory by situating career adaptability within a broader resource framework in relation to career success.
