Pros
Very stable company with a long and interesting history. Unique niche industry. Big, recognizable company name, but a small company feel inside the corporate office.
Cons
Most employees have been here 15 years, and many have been here for 25+ years. The company is stodgy and very stuck in their ways. Since so many employees have been working together for 20 years, new incoming employees are rarely treated as equals or even as part of the team. Anyone who has worked here for less than 5 years is treated as a "new" employee. This is a very clique-y environment to work in. For reasons mentioned above, employees and middle-management are very set in their routines and very opposed to change. They seem to believe that there is only one correct way of completing any given task. A lot of micromanaging goes on here.
