Career Opportunities Have Grown Along with the Growth of the Organization
The UPS management team, including the Named Executive Officers (NEOs), is comprised mainly of employees who have spent virtually their entire careers with us, and many would say they have had the good fortune of having more than one career at UPS due to the variety of assignments and advancement opportunities available across business units, functions and geographies. UPS has grown to include small package delivery; supply chain management; financial services; information management; freight transportation and delivery; consolidated mail services; and the operation of one of the largest airlines in the world. Our growth has resulted in greater career opportunities available to our best employees.
We believe the opportunity for career development and advancement within UPS builds loyalty, reinforces our strong corporate culture and reduces training and recruiting expenses. Ultimately these attributes provide a greater return to our shareowners. However, the high quality of our management team would not preclude looking outside UPS to fill an executive position if it was in the best interest of UPS and its shareowners.
