"U.S. Space Command (USSPACECOM) was reestablished as a combatant command (CCMD) in 2019 and has a diverse workforce of service members, civilian employees, and contractors. Its success will require a strategy to enhance and sustain the resilience of its personnel. In this report, the authors offer best practices for building workforce resilience by preventing and responding to four specific harmful individual behaviors that reduce organizational resilience: discrimination, sexual assault and harassment, hostile work environment, and self-directed harm and suicide. The authors conducted a literature review using military and private-sector sources, and they hosted six workshops with USSPACECOM personnel to identify the challenges and barriers to resilience program implementation. Drawing on these findings, they propose four recommendations to address these challenges and barriers."--
