Career is a complex term, and different authors define it in different ways. In the past, people did not consider this term to be so complex and important as now, and it was considered that when a person had a job, it was for a lifelong period. People used to start their job when they were young¿ and they used to stay in the same organization, and even at the same position, till they retired¿ It was taken for granted that a person if hard worker, reliable, competent, loyal and making no problems, would have a job as long as he/she wanted it. In return for such behavior of employees, companies offered them job security and stability of job. All the system, including organization and employees, functioned like a family, where the organization was the one that acted in paternalistic way. In those days career started as soon as a person finished his/her education and started to work, and did not require any additional knowledge of professional development.
