Today, it’s rare for someone to spend their entire career doing the same job at the same place. People may go to college or university to train for one particular job, but often end up doing various jobs throughout their lives. Though people may change jobs, they tend to use and build on similar skills in their different jobs.
This process of going from one job to the next is called a job transition. Sometimes people move to a different job because they want to try something else; in other instances, they may be displaced from a job.
