The COVID-19 pandemic affected every functioning system in the United States. Workers deemed "essential" faced multiple threats to their well-being that quickly led to acute symptoms of anxiety, depression, burnout, and overall exhaustion, and organizations were challenged to devise employee protocols to maintain sustainability. This qualitative study takes a tension-centered approach to discern how "essential workers" in the United States navigated this tenuous work landscape, particularly with regard to emotional work and workplace dignity. We conducted 19 semi-structured in-depth interviews with essential workers during COVID-19. Our constant comparative analysis of the data identified a macro-tension between vulnerability and sustainability that was revealed through two micro-tensions: (a) essential work as instrumental and disposable, and (b) workplace dignity as recognized and transgressed. We unpack the emotional responses enmeshed in these micro-tensions and situate our findings at the intersection of organizational sustainability, emotional work and workplace dignity. We offer theoretical and practical implications for essential workers and organizations.
