Pros

Its a great company the people are friendly and helpful. We have very good benefits and vacation time when you start at the company you are given 3 weeks vacation time and 2 personal days. Some departments allow their employees to work from home. There are several different sites so you may be able to work in a location close to home. Schering-Plough's campuses are very nice and they have cafe's on site and even a gym at one of their locations. We do have a PMP system so you know how your manager rates you, but often the feedback is minimal unless you are not doing your job.

Cons

Promotions - its a long difficult process to get a promotion even with excellent PMP ratings. It seems to be promised a lot but does not actually happen.
Lack of recognition - we have Shinning Performance program, but it is extremely under used in some departments. I feel that when people go above and beyond that they should be given credit.
Salaries aren't great and its difficult to get raises - if you come into the company at a low salary it is hard to get "bumped-up". I've heard that 10% is the cap, but I am not sure if that is true.

Advice to Senior Management

listen to your employees
recongize when something is done well and they go above and beyond
use the shinning performance to reward colleagues
don't continue to support colleagues who can't / won't do their jobs
