The Board of Directors has appointed Alain Dehaze as the new Chief Executive Officer of the Adecco Group. Alain Dehaze is currently Regional Head of France and member of the Executive Committee since 2009. He will take up his new role as of September 1, 2015.

“The fact that the Board decided for an internal successor stands for continuity. Alain Dehazeis a proven leader, with an international track record and profound industry knowledge“, said Rolf Dörig. “Alain Dehaze led his team to successfully turn around the business in France, Adecco’s largest market, in a very challenging environment. With his combination of strong leadership and people skills and his operational experience, Alain Dehaze will lead the Adecco Group to the next stage of success.”

“I am honoured to be appointed CEO of the world’s leading provider of Human Resources solutions – a company with strong core values, a great leadership team and more than 31,000 passionate colleagues around the world,” Alain Dehaze said. “The opportunities ahead of Adecco are vast. Indeed with increasingly volatile economies, there is a crucial need for more flexible innovative human resources solutions. At the same time, our candidates are looking for a career-long mentor in their professional development. Together with the senior leadership team and all our talented colleagues, I look forward to leading Adecco and seizing the opportunities for future growth.”

Alain Dehaze (51) is a Belgian national. He joined the Adecco Group in 2009 and since August 2011 has successfully led Adecco France – the Group’s largest market with 23% of total sales and 27% of EBITA in 2014. Between 2009 and 2011, Alain Dehaze was Regional Head of Northern Europe (comprising the Benelux and Nordic regions). From 2007 until joining Adecco, he was CEO of Humares, an international Professional Staffing company based in the Netherlands. From 2002 to 2005, he was CEO of the listed company Solvus.

Dominik de Daniel, Chief Financial Officer, has decided to leave Adecco at the end of July, 2015.
