Many many companies are like this. Most people are happy doing their very narrow range of things and put blinders on to everything else. They either don't have the time, interest, or energy to do more, and they learned to not really care what happens to the company beyond their own position... that's above their pay grade. If you attempt to make it easier for yourself to do more, you might wear yourself out too. The organization has become a demoralization engine, and some can continue on this way for a very long time. Some people might even be frustrated that you're trying to do anything differently. But sometimes you can make inroads, and you can make things easier for everyone.
