Adecco participated in the Hewitt Best Employers survey for 2009 and was ranked #1 among all the other 6 business process outsourcing (BPO) companies included in the research. The ranking is based on Hewitt's concept of employee engagement which is a measure of the energy, or passion, employees have for their employer or, more specifically, what their employer is trying to achieve. The survey is based on two main criteria – Employee Engagement Score and Alignment Score and Adecco scored the highest as compared to all BPO participants.
