Avantages
World Class Corp. that does many things well. Many opportunities to move career path and location. Shell is committed to workplace safety to some degree. They pay well and occasionally recognize great performance. Work life balance is good.
Inconvénients
The management structure is very narrow with too many managers and not enough workers, so when productivity appears low or a new CEO arrives, then a new or recycled program/reorganization gets implemented. This can be frustrating because these decisions always come from the top down without any input from the people doing the work. Highly technical people are not appreciated or respected unless you are a manager of technical people. Getting ideas implemented can be a challenge.
