Recently, the global economic and financial crisis has had a profound impact on working time. At the height of the crisis, work sharing - a reduction of working time to spread a reduced volume of work over the same (or similar) number of workers to avoid layoffs - was widely used as a job preservation measure. Following the crisis, the working time challenges have shifted: from focusing mainly on preserving jobs to an increasing focus on job quality issues - many of which are closely linked to working time, such as an expansion in jobs with short and often highly variable hours.
