This study investigates how daily fluctuations in job resources (autonomy, coaching, and team climate) are related to employees' levels of personal resources (self-efficacy, self-esteem, and optimism), work engagement, and financial returns. Forty-two employees working in three branches of a fast-food company completed a questionnaire and a diary booklet over 5 consecutive workdays. Consistent with hypotheses, multi-level analyses revealed that day-level job resources had an effect on work engagement through day-level personal resources, after controlling for general levels of personal resources and engagement. Day-level coaching had a direct positive relationship with day-level work engagement, which, in-turn, predicted daily financial returns. Additionally, previous days' coaching had a positive, lagged effect on next days' work engagement (through next days' optimism), and on next days' financial returns.
