Section C
We're now witnessing the emergence of an advanced economy based on information and knowledge. ____1____ Now, the vital raw material in our economy is knowledge. Tomorrow's wealth depends on the development and exchange of knowledge. And individuals entering the workforce offer their knowledge, not their muscles. Knowledge workers get paid for their education and their ability to learn. Knowledge workers engage in mind work. They deal with symbols: words, figures and data. What does all this mean for you? ____2____ Currently, three out of four jobs involve some form of mind work, and that number will increase sharply in the future. Management and employees alike will be making decisions in such areas as product development, quality control and customer satisfaction. In the new world of work, you can look forward to being in constant training to acquire new skills that will help you keep up with improved technologies and procedures. You can also expect to be taking greater control of your career. Gone are the nine-to-five jobs, lifetime security, predictable promotions, and even the conventional workplace, as you are familiar with. ____3____ And don't wait for someone to “empower” you. You have to empower yourself.
