Purpose. Building on the Kaleidoscope Career Model (KCM), this study investigated whether need for challenge, autonomy and balance predict intrapreneurial behavior, job crafting, work engagement and need satisfaction. Method. Data of 642 public servants (response rate = 58 %) participating in a 2-wave follow-up survey study with a three-month interval were analysed using SmartPLS2. Results. In support of the KCM, need for challenge, and not need for autonomy or balance, predicted employee intrapreneurial behaviour and job crafting. Crafting challenges and job resources at Time 2 followed from employee intrapreneurial behavior at Time 1. Intrapreneurial behavior and job crafting did not predict need satisfaction over time, but correlated with work engagement at Time 1, which did predict both challenge and autonomy need satisfaction at Time 2. Conclusion. Need for challenge is the driving force behind intrapreneurial and job crafting behavior, but the accompanying work engagement predicts need fulfilment.
