The purpose of this presentation is to describe a comprehensive vocational/career theory guided by research in positive psychology—the Strengths-Based Inclusive Theory of Work (S-BIT of Work). This theory was designed to addresses the ever-changing, dynamic world of work and integrates positive psychology, multicultural, and social justice values and research. Specifically, the S-BIT of Work aims to provide a holistic vocational theory to inform career and work counseling practice by increasing cultural sensitivity, promoting strengths and optimal functioning, and addressing a variety of vocational challenges across developmental stages. The primary goal and outcome of the S-BIT of Work is the experience of “fulfilling work,” which includes components of job satisfaction, meaningful work, work engagement, and workplace positive emotions. Fulfilling work is theorized to be influenced by contextual supports and barriers (e.g., access to resources and opportunities), a promotive work context (e.g., support, value alignment), and individual’s hope, strengths, adaptability, and empowerment. This presentation will include a discussion of the S-BIT of Work’s core assumptions and theoretical propositions, research supporting its development, and research and practice implications.
