There is alot of problems with this metric. First and foremost as that we need to redefine what "unemployment" means, as there are alot of people unemployed that do not count in that metric and conversely some employed people that are counted as unemployed.
The changing types of work (gig economy, etc) need to change how we count things.
Further Decreases in high paying jobs while creating low paying jobs does not seem like it should be something to be celebrated or pointed to as a robust economic activity, in short not all jobs are created equal
