-Diversity: Predominantly a white, male dominated company. Aon has made very little efforts to be more inclusive; the only time I recalled D&I being important is when clients informed us that they require brokers to meet a certain D&I level in order to do business with them. Look at the C-Suite - Aon doesn't care for minorities.
-Pay: They undercut your salary then wonder why they have high turnover on some teams.
-Culture: Working at Aon has been toxic. From people stealing items to making blatant, racist comments and "jokes" in meeting, I wouldn't recommend Aon to anyone. They lack respect for others and could care less at the end of the day.
