At least in Germany these things are connected, in that keeping people employed part-time, and not using fixed hours, serves to transfer risk from the employer to the employee, thus further undermining long-term social stability. Not to be too anti-capitalist about it, but one of the reasons societies grant rights to corporations is that they are supposed to move risk away from the workers and thus improve the buffer of economic stability. Obviously it doesn't always work like that in practice.

IANAStatistician, just pointing out that "hey look 5% unemployment" can be a very misleading statistic to use for laypersons.
