2.3.1. Issues Relevant to Advancing Worker Well-Being through *Total Worker Health*®

NIOSH has accomplished its goal of developing and publishing the research-centric National *Total Worker Health*® Agenda [12]. Another objective of the Office for TWH was to update a summarized list of seminal and current issues relevant to TWH and to the future of the workforce, to advance the scientific research focus and direction. Aside from the more customary workplace hazards that organizations have long faced, such as chemical exposures, traumatic injury, and shift work, workers and employers are also now navigating changing workforce demographics, growing work/life balance challenges, a multi-generational and aging workforce, and rising levels of work-related stress [20]. What is more, new work arrangements such as precarious or contingent work are often entrenched with increased exposure to hazardous work, little or no job security, minimal advancement and training, and a higher proportion of health insurance costs shouldered by the worker [20,21]. Therefore, in 2015, to highlight critical concerns to worker health and well-being, the Office for TWH published a list of these key issues that are relevant to advancing worker well-being through TWH (Figure 1) [20].
