The Happier, Healthier Professionals research programme aims to support the profession by understanding how local authorities might address rates of employee sickness absence and turnover by introducing interventions designed to alleviate stress and increase employee wellbeing. In this pilot, we will test whether providing social workers with access to free, high-quality tea and coffee in the office increases their wellbeing or reduces rates of sickness absence by increasing their sense of appreciation or recognition. Coffee machines will be randomly allocated to social worker teams, initially across 2 local authorities, and the impact measured over 6 months, between July 2019 and January 2020.
