Pros
A very well managed company with plenty of opportunity to learn and grow if you are a very hard working, workaholic type person and can maintain a positive, can do attitude regardless of whatever curveballs are thrown your way. The company's commitment to safety is first class and appreciated by all.
Cons
The drive for perfection and improvement is relentless. Results that earn you a bonus and an excellent review one year could be deemed inadequate and get your fired next year. Complacency is not tolerated. Nothing is really ever good enough. This is understandable in a highly competitive business. But it stresses employees to the max and makes it hard to maintain morale. Expect to work long hours and forget about being able to take any time off and don't get sick. The term "work life balance" is openly mocked by management. You are expected to make the company your first priority and any family obligations a distant second.
