The United States Bureau of Labor Statistics released a report in August which highlighted an interesting finding: the average person born in the later years of the Baby Boom has held roughly ten jobs between the ages of 18 and 40. These jobs were with different companies and not a different role within the same company.
Seems like a lot of job shifting. A new company every couple of years?
Looking back, I moved around quite a bit in my twenties. Various summer jobs. But, once I graduated from university, I did very little moving around.
