This book is dedicated to the four major types of return-to-work personnel movements: returning after time spent at another company, after long-term sick leave, after parental leave, and returning to an operational role following a period in a leadership position. These four reboarding scenarios are currently underrepresented in the professional literature. However, all four are essential for life-phase-oriented HR management and effective retention management. The book serves as a valuable practical guide for HR professionals and leaders, enabling them to implement these strategically important measures in a solution-focused way within their organizations.
