Between now and the 21st century citizens of the world's richest and most technologically advanced nations will find it increasingly difficult to keep up with the demand for change. For them, the future will arrive too soon. So begins Alvin Toffler's book FUTURE SHOCK, written back in 1970. Now people are beginning to pay attention to Toffler's prediction, because the speed of change is accelerating rapidly. It is sometimes difficult to work out the patterns of change. What should you do? First of all, don't panic. Take a deep breath and try to get a sense of the good things the future has to offer. You don't need to be a genius to predict the job areas which will be most affected by technological change. Agriculture, textiles, coal mining and heavy industry are all doing badly. On the other hand, business, the media, information technology, and the biosciences are doing really well. Without doubt, the number of jobs in information technology will rise dramatically. There are currently over 100 million computers in the world and by 2020 the number will be around one billion. Because of this, computer programmers and systems analysts will be in much greater demand. There are also many other important changes taking place in the workplace. First, the job market is getting more and more competitive and the idea of a "job for life" has already become old-fashioned. Because of this, workers will have to be more flexible. According to Mark Hastings of the Institute of Management, in the future people will organize their working life around a variety of contracts, instead of working just for one company. In the same way, companies will change; they will be organized more democratically. People will move sideways to different jobs, rather than moving up the "company ladder" as before. Many more people will work for small, dynamic companies, which can react, quickly to changes in the market. Other people will give up working for a boss and become self-employed. All this means that companies will require people who are flexible and responsible. They will also need people who can work co-operatively and get on well in a team. Good communication skills will be essential. According to Dr.Laurence Lyons of the Future Work Forum, women will initially have an advantage in this area. James Traeger, of the training agency Menswork, explains that many men will have to be retrained. "It's not about making men more like women, but helping men to communicate as well." We are undoubtedly moving towards a global economy. English will probably remain the international business language. However, understanding other people, their minds, culture and history will be vital. Above all, a manager will need to feel comfortable working with people from other cultures and coping with cultural differences. New technology is the driving force behind the rapidly changing workplace, so don't get left behind. You don't need to become a computer expert, but you must consider improving your computer skills. Work with more than one program in case you have to use them at work, and try to read about all the latest technology. Undoubtedly, all this new technology is changing the way we work and offering many alternative ways of working. Rather than go into an office, a lot of people are connected to the Internet and now work from home. Working like this may give you the flexibility you want - to live where you want, to continue your studies and to have a lot more free time. That must be good news..
