Pros
They gave us four weeks of PTO per year when they acquired our previous company. I am in a distantly remote office that was acquired by Cox two years ago; the things I like about my employment are largely residual from previous ownership.
Cons
The company I worked for was acquired by Cox two years ago, and my team has done okay because we have been largely out of the Cox corporate eye, doing what we are good at, making a lot of revenue for the company. But after two years they decided to shut down a lot of offices, and ours was one of them. My impression of Cox is that it is a family fiefdom rather than a meritocracy. It seemed some high-level decisions were made based on politics, long-time family friendships, and perceived loyalties rather than on business merit. They're an older company and seem to be struggling to bring their technologies and practices into the agile age. But at least they are trying to adjust.
