The biggest con is leadership/management, especially on the Burgess Source side. They are inexperienced, unorganized, promote toxicity, and promote an adversarial relationship between management and employees. They are quick to blame you for their shortcomings in management skills.
The PM work is driven by sales and managements desire to try and make as much money as possible. It leads to poorly written SOWs and little to no time spent on actual project planning. Almost every implementation hits a major delay at some point or another and the PMs are blamed for it every time (even when the product breaks, and continues to break or not be fixed for months or even years).
