Why Do Companies Have Different Employee Tenures

I was told by everyone I know in the industry that success is much more dependant on the office you work in as opposed to the company. However, when I look at the statistics there is a pretty big difference in the company wide retention rate of agents. For instance, MM tops the list of ALL companies (beating out Amazon) for shortest tenure which is .08 years. But then look at Metlife and you see that the average agent is there for 5 years.

So with that in mind, what would the dynamic be now that MM has bought the entire retail force of Metlife?
