Pros
I can't think of a single one.
Cons
Leadership is horrible; most are not qualified to lead. Can't recognize talent - it is all about who likes you. The department that I worked in was lead by a glorified admin who was a tyrant. She caused drama, was nasty (may even be a sociopath), and treated high level employees like dirt. Those who were less talented and less capable than her were always rewarded; if a person in the department was well liked, praised, experienced - she was threatened and made it almost unbearable to work for her. I can't even begin to quantify the number of unethical, illegal, and discriminatory practices that took place during my time there. It is shocking that this person has remained in her role for as long as she has. In conversations with other employees, my experience was not unique. When problems arose, this leader would blame her direct reports - and deflect attention from the true problem: her.
