Trade unions, refugees and immigrant labour: Has the attitude changed? The stance of Swedish blue-collar trade unions as evidenced by sentiment analysis

The attitude of trade unions towards migration and migrants, be it of asylum seekers or those in search of jobs and better incomes, differs substantially across European countries. No matter the original stance, a common current pattern is that of the willingness to accept migrants being eroded over time. To see whether this is the case also in a country that both proved welcoming to labour migrants and refugees during the opening decades of the new millennium, we set out to explore the attitudes of blue-collar trade unions in Sweden. Based on a diverse set of material issuing from the unions themselves, we use sentiment analysis to assess whether there are any changes to be discerned in the opinions of the representatives of 12 blue-collar trade unions and their national confederation. At its most general, the trend appears to turn more negative over time, yet the influence of defining events and legal changes is not so easily observed at the aggregate level. The union representing workers in the industry with the largest proportion of immigrant labour, the Hotel and Restaurant Workers' Union, is therefore selected for closer analysis. To the extent that changes can, or cannot, be observed, we relate those to major events and policy changes that have taken place over the 2010s.
