I'll start with the pros. You get to set your per-word price as a writer, and you can also build up a nice catalogue while writing for yourself and/or other content companies, which is what I did.
The cons? Constant Content takes a whopping 35% of every sale and does very little to earn that money. So self-promotion is mandatory because a lot of writers are selling their content for peanuts.
The biggest con would be dealing with the editors and their respective quirks. Most of the Constant Content editors that I dealt with were knowledgeable and professional in spite of their quirks. However, there was one editor in particular who was rude, entitled, a liar and laughably incompetent. This became more evident whenever I wrote about subjects that were clearly outside his/her wheelhouse. And as luck would have it, I soon found myself dealing with that insufferable [rear orifice] most of the time, which is why I quit.
My advice to management would be this: Remember that writers are your bread and butter.
