A Holistic Approach To Leadership Development And Self-Efficacy For Frontline Managers, Alberta Green

Dissertations

According to Clifton and Harter (2019), managers determine an organization’s success. Specifically, managers determine 70% of worker engagement. Researchers (Bandura, 1997; Dwyer, 2019) have associated self-efficacy with leadership strengths. As such, frontline managers (FLMs) need holistic leadership development (HLD) training in the four leadership domains—analytic, conceptual, emotional, and spiritual—to improve their competencies and bolster their self-efficacy (Clifton & Harter, 2019; Ward, 2018). Integrative leadership development models that prioritize organizational resources through holistic leadership development offer a modern approach to addressing FLMs’ leadership skill development and self-efficacy (Guidi et al., 2018). According to Bandura (1997), self-efficacy is how individuals evaluate their …
