Good place to learn about the business, but you're just a number and an expense item - Consultant Aon Employee Review

Aon grew through acquisitions, and there is no central database of anything. Like any big firm, you're just an employee number and an expense item on their balance sheet. The company used the current economic climate as an excuse to freeze salaries, cancel carryover vacation days, freeze pensions, and even take away employee awards every five years with the company just to name a few things. It doesn't help morale when they announce the most lucrative sporting sponsorships after all these cuts.
