“…Selwyn (2013) mentions three main limitations: first, the ILO's concept of social upgrading 6 has limited power and its real impact on companies' behaviour is modest; second, little is said about the processes and mechanisms for social upgrading; and last, the exploitation of labour tends to be downplayed, focusing instead on institutional arrangements between state, capital and labour, which ignores the real reasons for labour inequalities. Wages alone are not any sufficient indicator of social upgrading, and are not any reliable gauge of working conditions in the broader sense either (Bernhardt and Pollak, 2016). A broader view has been taken, among others, by: Lee et al (2016), who consider -in addition to wages -hours, overtime, hiring and contract practices, as well as health and safety conditions; by Kabeer and Mahmud (2004), who associate working conditions with permanent job status, maternity benefits, paid leave, accommodations, medical care, and overtime pay; by Barrientos et al (2016), who define social upgrading by work opportunities, measurable labour standards and enabling rights; by Bair and Gereffi (2001), who focus on safety, exploitation, compliance with local labour laws, and sanitary conditions at the workplace; by Rossi (2013), who considers work environment, overtime, job and social security, as well as enabling rights.…”
