Psychosocial safety climate (PSC) is a term used in organisational psychology that refers to the shared belief held by workers that their psychological health and safety is protected and supported by senior management. PSC builds on other work stress theories and concerns the corporate climate for worker psychological health and safety. 
Studies have found that a favourable PSC is associated with low rates of absenteeism and high productivity, while a poor climate is linked to high levels of workplace stress and job dissatisfaction. 
PSC can be promoted by organisational practices, policies and procedures that prioritise the psychosocial safety and wellbeing of workers. The theory has implications for the design of workplaces for the best possible outcomes for both workers and management.
 PSC theory is a work stress theory in the field of workplace health and safety and organisational psychology. PSC refers to the shared perceptions of employees of their organisation’s “systems, policies, practices and procedures for the protection of worker psychological health and safety”. PSC largely reflects management values regarding the psychological health of workers.
 PSC theory is that when senior management value and prioritise worker psychological health and safety, corporate decisions are made to provide and design work that is meaningful, manageable, amply resourced and free from psychosocial risks. Numerous work stress theories exist within occupational health psychology, work and organisational psychology, and work health and safety disciplines (Job Demands-Resources Theory; Job Demand Control Theory). These are major job design theories that emphasize that work stress arises largely from the way work is designed (‘the cause’), such as when the requirements of the job (demands) outweigh one’s capacity to perform with the resources available, job stress occurs. 
 PSC predicts future work design, such as the level of demands a worker will be exposed to and the amount of resources that will be available to carry out job tasks. PSC is therefore proposed as a ‘cause of the causes’ of work stress, a cause of stressful work design and other work conditions.
 Psychosocial safety climate is composed of four subsystems:
 PSC is related to safety culture, perceived organizational support, and psychological safety but is a distinct construct. Safety climate concerns the climate that protects workers from accidents and injuries and emphasizes safe systems and safe worker behavior.
 PSC research has been undertaken in Australia, New Zealand, Malaysia, Japan, China, Iran, Ghana, Vietnam, Netherlands, Norway, Germany, Portugal, India, Sweden, France, Canada, US, and Spain, across many industries / occupations. Evidence shows that PSC predicts workplace psychosocial risks and health and productivity outcomes.
 PSC predicts psychological distress and emotional exhaustion, depression, exhaustion and cynicism, sickness absence, presenteeism, work engagement, and workers’ compensation claims for physical injuries, work injuries, injury underreporting, stress-related concerns reporting, safety behaviors and performance and turnover intention.
 Studies show that PSC can change through organizational and individual interventions. Participative organizational intervention research shows significant improvements in PSC within a 4-month period for interventions aimed to tackle work stressors focusing on the PSC principles.
 PSC concerns the system of psychosocial risk management in organizations and covers crucial elements of the NSW SafeWork Code of Practice 2021 and Australian WHS regulations. The fundamentals of a psychosocial risk management system are captured by PSC. PSC has been used as an evidence-based evaluation indicator for the Australian WHS policy change. The Regulatory Impact Statement concerning WorkSafe Victoria’s 2022 proposed amendments to the Occupational Health and Safety Regulations 2017 to improve workplace mental health, indicates that PSC could be used as an indicator for future policy evaluation efforts.
