Has the ideal of being a single company employee become a thing of the past? An employees longevity has always cast a loyal, steadfast and trustworthy impression, compared with that of a CV littered with multiple positions which could be seen unfavourably by a prospective employer.
On the other hand, staying too long in a job could hinder your employment prospects. A lengthy stint with one company can give the impression that you aren't interested in progressing your career or that you may not have the flexibility for success in a new role.
These days changing jobs frequently has become the norm rather than the exception, and employers now seem to be realizing the potential benefits. Newly hired employee's, among other reasons, can bring market information about competitors whilst also tending to be top performers.
It's a difficult one to call, and I'm sure there will be many different views. One thing is certain, that the job market these days is considerably more open to the benefits of both.
The hallmark of the “grass is greener syndrome” is the idea that there is always something better that we are missing. So rather than experiencing stability, security, and satisfaction in the present environment, the feeling is there is more and better elsewhere, and anything less than ideal won’t do. Whether it’s with relationships, careers, or where you live, there is always one foot out the door.
