Pros
Very relaxing low-pressure environment. Very inclusive, multicultural corporate culture. Heaven for subcontractors. Because there is no responsibility for end result. Salary on par with market price. If your Dream-Job is to have no personal responsibility, if you would like to be judged by how many Hrs. you work, how much you available on off shift Hrs. without any implication of achievement, than Cummins is for you.
Cons
Cummins culture (as a minimum at Rocky Mount NC Engine Plant) is a great failure. Quality is steadily falling. Technical problem being dragged on for years without even attempt to solve. Retention of Engineers are very low. As a matter of fact I do not know any engineer younger 45 years old who works for Cummins (not as a manager) without string attached (work Visa, tuition reimbursement e.t.c.) My advice to young (as well as not that young) engineers: If you would like to be judged (and promoted) based on your accomplishments, not working Hrs. If you prefer to take responsibility for your decisions, not blindly follow numerous contradictory instructions. If you want to make a difference, not just work 10 Hrs. a day. That you should avoid Cummins at all cost.
