Labour market specialist Jan Denys told the VRT that people find work important, but they also want spare time for their family or their leisure time. This applies both to women and men: in 15 years' time, the number of men opting for an 80% schedule more than tripled.

The "80% formula" has become so popular, that there are now more women opting for this roster than there are women working half-time. 15 years ago, this was just the opposite. "Call it the new full-time job", Denys says. "You could say that labour times have shortened."
