What are the possible reasons that computer usage in most of organizations can lead or contribute to unemployment?
This is an interesting question. I suppose there are a couple of ways. As computers eliminate jobs, there will be more people unemployed. Also, the increase in social networking sites and other inappropriate web sites might lead people to be fired for their web activity. Companies are also now reading people's e-mails and firing them based on what's on their Facebook pages. Now it is more important than ever to be careful what you do on the web.
I would agree with both posters on this topic. While computers are more efficient and could lead to expansion, they also cna lead to downsizing in situations of automation. There are computers that can now run an entire assembly line. I would also add that there is a loss of jobs for those Who are not able to run the programs on the computers.
I agree that computers reduce the need for "manpower" but I would say that Post #2 understates the extent to which computers can reduce the need for people. It is not just data processing -- computers can run machines now, for example, where actual human beings were once needed.
If you are taking an economics course, you should note that this is an example of structural unemployment -- when workers lose their jobs because those jobs become obsolete (in this case due to computers).
In general it is not true that computer usage leads to unemployment in organizations. There is only one way in which computer usage can reduce the need for manpower and therefor lead to unemployment. But usually computer usage usually helps to improve business performance. This leads to expansion of business, and with that, increase in manpower. Further, use of computer also frequently directed towards improvement in performance of people rather than reduction in man power requirement.
Computer usage reduces manpower requirement for the job performed by the computers only when it is used for performing data processing tasks that were earlier done manually.Computers performs these tasks much faster, economically, and with substantially lower manpower inputs as compared to processing of the same data manually. The is the only reason for which computer usage can contribute to unemployment.
