Throughout most of the 20th century,a high school diploma was usually enough to assure a job .In fact,many large companies operated their own internal training and development programs for recent high school graduates.Recent changes in the global job market have put an end to those traditions.Very few people experience the stability of working for only one or two employers throughout their careers.In fact,most workers entering their first job today will change career paths at least seven times before they reach retirement age.
