Pros
Because of their sheer size, they should have the potential to be very powerful. They have the potential to negotiate preferential benefit packages.
Cons
Because of their size and their inability to communicate within, they are ineffective. Bureaucracy runs rampant at AECOM. There are so many procedures and policies related to enhancing their stock value that project performance suffers. Much of the day is spent reading pat-me-on-the-back emails not related to client satisfaction. Legacy URS employees have seen a gradual decrease in benefit value since their acquisition and it seems to be shrinking daily. Transparency in this regard does not exist. Technology is proclaimed to be a priority for AECOM, but apps and software are full of holes and inadequate. IT is overwhelmed with no help on the horizon. It seems as though AECOM is forcing its workforce to downsize itself by "natural" means. Contrary to what they say, it is not a friendly place to work.
