Pros
In the IT sector, the benefits and pay at GSK are above the industry for people coming out of college and contractors. They advocate a work-life balance and encourage people to look after their health in addition to your performance. The people who work there are quite experienced and look out for one another.
Kontras
GSK is a huge company with many departments so the bureaucracy can neutralize new ideas. Each department has its own unique culture depending on the management so I've seen people who feel completely open and able to bring themselves to work while other departments, it can be quite stifling. Pay and bonus is kept very secretive despite the move towards transparency. At times, it feels like the bonus and pay is more based on how long you've been at GSK and less based on business performance. Recruitment tends to favor applicants with a pharmaceutical background. Unfortunately, that leads to the same type of thinking and ideas. New ideas are rarely introduced because if they fail, the bonus will also be affected. The company is very risk adverse (rightfully so in certain areas because of regulatory reasons) but it spills over into areas that need not necessarily so.
