Pros
You meet a lot if good-natured people with positive attitudes, but only untill they realize that promised opportunities were just carrots on a stick to get something out of them. In our division there were few people left with more than 8-10 years experience. That seemed to be the point where employees gave up trying to work with management and left. You could see people's demeaner and attitude change the longer the were with us.
Cons
They keep the carrot and hit you over the head with the stick. In 6 years with the company I saw lawsuit after lawsuit by employees and vendors. Roche has the attitude that they're too big to lose a lawsuit, so they basically enter into contracts and, after getting what they want, they walk away from their end. Most co-workers complain that Management approaches them with promises of promotions if they add extra work and assignments. After the Managers get what they want, there're no promotions. Another common practice is that you can't "resign." Many, many ex-employees have found that they can't use Roche as a reference because, when you resign, HR puts "Terminated" on your record. Roche is so paranoid of employees going to the competition or a vendor that they trash your record to keep you from finding another job. This is begging for a class-action lawsuit. Each month our department sent an e-mail with the names of employees no longer allowed on the premises and that security should be notified if they were seen. Each month there were at least 3 new names. It got to the point of absurdity. Whether those employees were fired, or resigned and then labeled as having been fired is unclear. But with what we knew of HR's practice of labeling all ex-employees as having been fired, it really crashed moral.
