Summary	Affective Events Theory (AET) is the macro framework that reoriented organizational research toward emotions and the events that cause them. Proposed by Howard Weiss and Russell Cropanzano in 1996, it argues that features of the work environment give rise to discrete events — daily hassles and uplifts — that trigger affective reactions, and that these momentary emotions, not just stable attitudes, drive how people behave at work. The theory's central insight is to distinguish affect-driven behaviors, which flow directly from emotional states, from judgment-driven behaviors, which flow from evaluative attitudes like job satisfaction. It also positions dispositions, such as trait affectivity, as shaping how strongly people react to events. Weiss and Beal's 2005 reflection clarified the theory's structure and its methodological demands, especially the need for within-person, over-time data. AET supplied the conceptual rationale for the experience-sampling and diary revolution in organizational behavior.	The Utrecht Work Engagement Scale (UWES) is a 17-item instrument measuring work engagement—a positive, fulfilling psychological state characterized by vigor, dedication, and absorption in work. Developed by Wilmar Schaufeli and colleagues in 2002, the UWES operationalizes engagement as the positive antipode to burnout, reflecting energetic involvement, strong commitment, and deep focus in occupational tasks. The scale has become the standard measure for assessing work engagement in organizational research and occupational health.
