Pros
Stability, and retirement. Union Pacific has a good franchise. When one segment of the economy declines, another raises. Union Pacific has been in business for over 145 years. The company invests heavily to grow capacity and provide better value to our customers. Unlike some companies, Union Pacific is not in it just for the stock price. From where I sit, decisions are not made with regard to how it will affect the stock price. They are made on sound financial business principles. Over the last several years, Union Pacific has been working to become more efficient with out cutting headcount. This dedication to employees is one of the reasons there are so many people with more than 30 years with the company.
Cons
It's big. While this does provide stability, it does not mean they are agile in meeting business needs. The complexity of having a diversified franchise also makes managing that network difficult. Growth opportunities: I work in information technologies. There are three career paths in IT. At a very high level there are job descriptions. There is no description / path / game plan of how to get from one position to the next. For performance tracking, Union Pacific uses a product called Total Performance Tracker (TPT). This allows only for your direct manager to give you feedback. This feedback is only provided two times per year. It would be much better to use a 360 type approach where your customers, peers, etc. all have the opportunity to provide you with feedback. Without good feedback, how is any employee expected to know what he or she is doing well, let alone focus on areas needing improvement.
