Aon Best Employers–About the Program

About the Aon Best Employers Program

The Aon Best Employers program recognizes the achievements of organizations that demonstrate excellence in the workplace. With a consistent methodology, we measure and recognize employee excellence, anywhere in the world.

Reliable Approach: Your Employee's Opinions

Our research proves that Aon Best Employers drive consistent long-term performance through organization cultures marked by effective leadership, strong talent focus, agility and high employee engagement.

These four measurable factors contribute to whether an organization is named an Aon Best Employer.


Employees speak positively about their employer, intend to stay and are motivated to exert extra effort at work.


Employees see that the organization is highly adaptive, innovative, inclusive and responsive to the changing needs of its customers.

Engaging  Leadership

Leaders are deeply connected with employees to drive engagement, communicate a clear vision and exert strong personal values.

Talent  Focus

The organization is focusing on attracting and retaining great talent and accelerating people's potential to the extraordinary.

The methodology used to determine an organization's qualification as an Aon Best Employer is based on the most objective measure possible: your employee's opinions. The approach we use is an integral part of Aon's employee engagement methodology.

Using survey data collected from employees, the four indices described above are calculated for each organization at country level and then compared to relevant Aon thresholds using our global employee engagement database. Aon's database for the last five years contains data representing the opinion of almost 9 million employees from more than 5,000 organizations around the world. The thresholds are determined by analyzing the data from these organizations and are refreshed bi-annually.

  • 5 years of data
