Samfunnsøkonomisk analyse and Fafo are going to survey experiences with the HSE card system. The project aims to illuminate how the HSE card system in construction and civil engineering, cleaning, car maintenance, tire changing, and wheel storage contributes to reducing the incidence of labour market crime (a-crime) and social dumping. This includes assessing the extent to which HSE cards are subject to abuse, proposing measures to reduce such abuse, and enhancing the effectiveness of HSE card systems in reducing labour market crime and social dumping.
