Pros
Easy to work there, low expectations, anyone who is moderately good is a "star performer". Flexible schedule - management doesn't keep track. Most people work 9 to 4:30. No travel - except for in specific very high level roles, but this is damaging to some customer facing and product management roles.
Cons
You can't get in front of your customers. Product managers are expected to do all of their work from the office, and therefore are unable to really see what their customers need or how they use the product. A lot of lazy people work at Cummins - because it is nearly impossible to get fired for mediocre performance. So - you have a few "A" players, very very few, and a lot of people who want a job for life and do hardly anything at all. It's a frustrating environment for "top talent" which is why they leave in droves every single year. Cummins also prides itself on paying just below median - which also attracts middle level talent. I mean, who stays somewhere, when you are practically guaranteed a higher salary somewhere else. As a manager you are expected to "work with" people who are not performing - which leads you, as a manager, to convince other managers to higher them, thus continuing the cycle. Very high turnover, due to high performers and low performers both, means that there is no continuity in jobs or management. I had a new boss every 6 months, along with their expectation for my role. HR runs the company - employees are existing in an environment where they are terrified to say anything to anyone. It's like a stasi state you are encouraged to "report others anonymously" for "coaching". Also, the hiring of employees on visas is an intentional tactic to keep wages very low. People are hired on visas, when there ARE qualified Americans, I was told to "ignore that fact" and just process people through the system in order to increase diversity numbers. When choosing between 2 candidates you are supposed to hire the "diverse" candidate even if they are substituting for an American worker. Indian tech workers are sequestered in a windowless building in Columbus - but there are hundreds of them from outsourcing companies.
