One of the biggest con was the change in middle management. Although some things needed to be fixed and required their guidance and experience, other areas of the company were not actually "broken" and caused major disruption to staff. It was sadly some of the more experienced staff (tenure 3+ years) who shared any difference in opinion (even though that was strongly encouraged) that were hurt the most. Sadly, as the company is growing and doing exciting things, the employee appreciation and moral has diminished, usually if you weren't hired by this new management.
