Many reorganizations, office politics, bad supervisors and middle managers
Pros
You could gain many skills and hands-on experience while getting a market average base salary with an up to a 8% of your base salary to your 401 K from the company match and a more than 10% of your base salary to your pension plus an usual more than 10% of your base salary as your normal annual bonus. Some senior top managers care about employees.
Cons
There are very lousy on-job training, frequent reorganizations (every one or two years, depending on business units), awful office politics and many bad supervisors and middle managers. Many employees who are good at "talking" in front of management with mediocre performance are usually promoted faster than quiet hard-working employees. Employees who have two faces or are good at office politics are quite popular. Many supervisors and middle managers care about only their own promotions. The values of the company printed on the brochure stay just on paper in most of time. There are exclusive, office bullies, discrimination and retaliation work environment supported by the direct supervisors and middle managers in some business units.
