Pros
Most managers in the IT Department (IMS) don't know exactly what you are doing, so you have some control of your day-to-day interactions. If fact, some people can work from home one or two days/week, which is great.
Cons
Managers are vindictive. They don't communicate, and it seems that they derive pleasure from writing people up (it is called placing people on PIPs). Some joke that managers have a contest to see how many people they can do this to. My former manager would write someone up so that others would work harder (motivation by intimidation). She is good friends with senior leaders so she is not going anywhere but up. The worst part is that she would gossip about others in the area, thus destroying her team. more than 50% turnover in 6 months and people don't care.
