For most people, when they get their first job they have little idea whether or not they will remain in the same organization throughout their working life to change, they need to consider how this will impact on their career overall.
People who stay with the same organization have the advantage of how it works and also becoming familiar with the staff and processes hard, their promotion prospects are good and there is likely to be greater job security, with the promise of a good pension when they retire loyalty and may offer additional incentives to long-term employees, including bonuses and reward schemes.
However, one of the drawbacks of staying with the same organization is that the person may get stuck doing the same job year after year, this can lead to boredom and disillusionment one organization to another can be a strategic decision in order to have a variety and acquire a range of skills and experience. a friend of my father started out as a sociology teacher, he then joined the social services and is currently managing a care home in Western Australia him incredibly knowledgeable in a range of related fields and, in my view, has provided him with a much more interesting working life.
Although there are benefits to working for one that it is also valuable for an employee to be able to offer a wide range of experience having worked for different companies it is planned carefully, I feel that change is good and will ultimately benefit the employee and the employer.
