Pros
GSK has competitive wages and compensation. They Strive to be professional in their dealings with personnel and the public. Their products are usually of high quality and offer unique advantages to patients.
Kontras
GSK has become so large that they now place legal liability as their driving concern. Sales plans are now so restricted and ultra conservative that they seem written directly by the legal department. If you have to ask whether you can do something the answer in inevitably, "no, let's just be safe". Sales goals and compensation plans are also so one-size-fits-all that they can not adequately compensate for huge differences in marketplace demographics and trends. Better hope you work in a growing city in the south, especially Florida, if you want consistent bonus opportunities.
