Conclusions
SUH is an adaptive, flexible, multi-component intervention that allows contact centres to develop a range of activities to suit their culture and context. The process evaluation findings showed that the intervention was acceptable and feasible to deliver, and most contact centres implemented several actives aligning with every level of the programme’s theory of change. Perceived subjective benefits such as reduced sedentary behaviour, increased physical activity, and improved staff morale and mood were reported by contact centre staff and managers. After the COVID-19 pandemic, most organisations have adopted a hybrid working format, and further research is required to understand and develop appropriate activities for this new work environment. The SUH programme shows potential in reducing sedentary behaviour and positively impacting several health and wellbeing outcomes in contact centres, and can now proceed to large-scale evaluation.
