As to whether people should be encouraged to change their jobs frequently, there arises a contentious discussion. Personally I am of the opinion that we should not hop from job to job. It is undeniable that job-hopping is becoming a growing trend in today’s workforce. Moving from job to job every couple of years is looked upon as a way to move upward in responsibility quickly and keep skills fresh and up to date. However we shall never lose sight of the risks of changing jobs too often. Tradition tells us those who spend years and years at one job, in one office, in one city are stable. Often, stability equals success. Moreover, if you were a chronic job-hopper, people may be questioning your integrity and loyalty. Employers don’t like to see resumes filled with short-term jobs. They would rather hire a person who has commitment and devotion to an employer. Job switching too rapidly makes employers think the individual can’t get promoted, isn’t reliable, can’t be a team member, or is so egotistical or self-centered that no job can meet his or her expectations. From the above discussion, we may safely arrive at the conclusion that it is not always advisable to hop from job to job. An old saying may well illustrate my view, "Jack of all trades and master of none." Job-hopping: broaden your experience before sticking to one / fresh life with every new job / willingness to learn / find your strength through trying different jobs / great challenge to Sample Presentation: I think changing jobs can be a good thing because you can broaden your experience and also the likelihood is that by having tried different things you are more likely to settle on something that you want to stick with for a bit longer. Also I guess that one thing about modem economy is that flexibility is very highly valued. That does mean that we don’t really have jobs for life any more, which a lot of people find quite difficult. But then I think that there is a new generation which has adapted quite well to that. The other thing is that there are so many new jobs that didn’t exist perhaps B0 years ago, they exist now. And perhaps older people haven’t had the chance to do them, so I think there is a big generational difference in terms of our attitudes to finding work and also how long we stay in each particular job. Especially for your young people, when you leave university and you don’t necessary know entirely what you want to do. Some people have a definite career path they want to follow; but if you leave and you’re just not sure quite what you want, I think it’s good to move around and try different things.
