Cons
The worst part of Cummins is the forced ranking and firing. Every year managers are required to rank their employees and then a set percentage of the bottom are fired. This worked well the first few years it was mandated but now Managers are loosing good employees. Also this forces a competition between employees and hampers team work. It has become more of a "favorites" system, and highly capable employees are choosing to leave since job security is not available. They are leaving to go to companies where they do not have to walk on egg shells trying to not be the person ranked the lowest.
