Studies by Industry
In examining the average years of job duration for employees based on industry, the service occupation for food preparation and serving jobs had the least number of average years of tenure to indicate any workforce turnover.
However, there was an increasing length of period by which an employee stayed on, as noted by trending the survey results:
Year 2000 = 1.6 years; Year 2002 = 1.5 years; Year 2004 = 1.8 years; Year 2006 = 1.8 years;
Year 2008 = 2.0 years; Year 2010 = 2.3 years
It can be surmised that employees held on to jobs for food preparation and serving at an average of 1.5- to 1.8-year durations before they made any moves for job changes. In years 2008 to 2010, which were the heightened periods of recession, employees held on to these jobs much longer.
Still, for those who were separated from this particular industry within a short span of time, it would also be difficult to readily surmise this as due to career change. A co-related article which showed a trending of job loss statistics revealed that mass layoffs in the food retailing industry was still prevalent in 2010. See my separate article entitled “A Look at Trending Job Loss Statistics".
Based on this, we are now clear why there should be a definitive set of guidelines for defining career or job change in order to come up with a plausible survey to measure just how many people change their jobs each year.
