Purpose Within large and complex organizations work disability (WD) communication bottlenecks emerge and contribute to avoidable disability days. Our study utilized soft systems methods to better understand communication problems in WD management. Methods Semi-structured interviews were conducted with disability case managers (n = 10), frontline supervisors (n = 15) and human resource/labor relations specialists (n = 5) within three public service organizations. Interview questions asked about organizational WD system structure and communication practices. Thematic analysis was conducted to examine system structure and emergent communication bottlenecks. Results WD communication took place across a number of internal and external stakeholders. Communication bottlenecks tended to concentrate within WD case manager and frontline supervisor activities. Inconsistent communication across organizations, challenges interacting with external stakeholders, mental health disability information exchange, lack of WD communication experience and previous worker performance represented communication bottlenecks that contributed to avoidable disability days. Conclusions To strengthen communication practices, systems-focused responses towards organizational WD management are required.
