The widespread adoption of communication technologies in professional contexts has significantly transformed workplace communication practices, often leading to communication overload and negatively impacting Quality of Life at Work (QLW). This paper presents the VERTUOSE project, which aims to develop a Socio-Technical System (STS) for regulating workplace communication. Utilizing a co-design approach that integrates sociological, IT, and co-designers' perspectives, the technical part of the system aims to be open and adaptable. The STS provides tools for managing communication practices through customizable policies. Key challenges such as data privacy, ownership are addressed through transparency of data handling and informed user consent mechanisms.
