The attached graph shows the unemployment rate (those who are looking for work but can't find a job) and the underemployment rate (those with some part time work but who want to work more) over the last ten years.
Two points to note. While movements in the two curves generally mirror each other, you can see how the gap has widened over the least two years. I think that reflects in part the continued rise in part time work. The second point is that the combined total of those out of work or who are underemployed is now well over 14% of the workforce.
So what we appear to have is a steady increase in the combined un/under employment rate at the same time that the work force is declining as a percentage of the overall population.
Just at the moment, the country needs to maintain workers as a proportion of population and increase the utilisation of those who want to work. I don't think that we are doing an especially good job of either.
