The legal transposition in Sweden of international law on forced labour is analysed and important weaknesses in the implementation and application of such law are identified. These deficiencies are illustrated by the treatment and means of redress available to foreign berry pickers who annually gather wild berries in the forests of Sweden. A case study of the recruitment and employment of Thai berry pickers is presented, exemplifying serious deficiencies in labour protection both in terms of legal recourse and regulation through the labour market. As a result groups of berry pickers have been subject to various illegal forms of detriment amounting to evidence of forced labour. A number of policy recommendations are made for strengthening the legal and labour market regulatory framework to enable effective control of forced labour in this sector of work in Sweden.
