Pros
As someone already mentioned some of the people who are left are not as bitter. It's hard to come up with positives, when the atmosphere has been poisoned by the existing managers and directors
Cons
I see a number of reviews of the IT department here already and I can't add much more to that. Most of the people left have to answer to incompetent managers who are self serving and have no interest in your wellbeing. Offshoring is the norm. There is no interest in living corporate values. Crazy deadlines abound. Decisions are made in a political fashion with absolute no regard for fairness or equality. No training. No skills development. Work after hours is expected since planning is so poor or non existent. CIO is on the fast path to destroying this company
