Pros
Very flexible work environment (can work from home, work from other offices, hours are generally flexible), great local community within the office, no local profit centers thus work sharing across offices is encouraged.
Cons
The company is adjusting to the continually shifting engineering consulting industry. As the environmental industry has struggled to rebound since 2008, the company has undergone restructuring within the US (where the environment business line has previously been dominant), which has isolated employees from the upper management. Most employees would agree that their local teams are great, but cost-savings maneuvers (bonus reductions, overhead cuts, office closures) required to remain competitive have resulted in some general feeling that the company isn't "paying attention" to it's employees. In my opinion, it's more due to company size and the shifting industry than malicious intent on behalf of management as some current and former employees seem to think. The primary negative is that Arcadis is a company with a goal for growth despite continued growing pains from previous acquisitions and decreasing margins from previously profitable market sectors.
