Most of the examples were blue collar and it's not hard to see why there might have been more sick days the past few years.
On the other hand with more flexible working arrangements for some workers, it's also not hard to see why someone not feeling well might literally phone it in for a couple hours rather than taking a formal sick day.
Without a lot more data I'm not inclined to conclude a lot from a few numbers.
