Paid work refers to time contracted out that receives remuneration. Work arrangements and the extent to which paid work is performed under decent conditions show extreme variations, with notable consequences on workers. Informality and lack of decent work conditions have received considerable attention worldwide by government and nongovernment organizations, trade unions, and the International Labour Organization (ILO), as well as academic researchers. Labour market segmentation, wage differentials, unemployment, and labour force participation rates are also relatively well investigated subjects and national labour statistics departments routinely collect data on these issues. Unpaid work has received less attention and we now turn to this.
