The agency said that in his new role, Duncan will lead the employee engagement and change management practice across EMEA, providing consultation for clients in a wide range of sectors.
In his previous roles, Duncan has advised clients including BP, GSK, Nomura, Shell and Thomson Reuters on their employee comms and engagement strategies.
Ben Burton, MD of corporate at Weber Shandwick, said: "Increasingly we are helping our clients put employee engagement at the heart of many of their campaigns and communication programmes, be that through traditional means or increasingly digital and social channels. Stephen brings incredible experience of working with the world’s top businesses and will bring new thinking to our clients as we expand our offer."
Duncan, who will be based in London, said: "The market for employee engagement is maturing very quickly in EMEA as the value of this approach is recognised as delivering great results for businesses. I’m looking forward to working with Weber Shandwick’s global employee engagement team and building on the great offer it has already created."
Duncan is among a number of new appointments at the Interpublic-owned agency, including James Nester of We Are Social as its new executive creative director plus additional members to its digital team.
