Cons
Prior to Sanofi's acquisition of Genzyme Corporation, Genzyme's employees were a "family", a culture that the corporation actively promoted. Employees were inspired and highly motivated to achieve company goals and as such, they were rewarded, not only through salary, but also by stock options. Management was fair, approachable and truly dedicated to helping its employees advance. After Sanofi's acquisition, the "family culture" disappeared. Employees were no longer rewarded with stock options, management was no longer approachable, nor dedicated to helping employees advance. As a result, Sanofi experienced an extremely high attrition in stark contrast to Genzyme's extremely low attrition.
