Luca Michele Cigna has written a master’s degree thesis about trade unions’ positions on Basic income: Looking for a North Star? Trade unions’ positions in the Universal Basic Income debate

First, unions’ propensity to support a UBI depends on
the degrees of socio-economic insecurity. In contexts characterised by high levels of poverty,
unemployment and precariousness, UBI proposals look more attractive in the eyes of union leaders.
Secondly, welfare regime generosity is a strong explanans of trade unions’ support. Less
encompassing welfare systems encourage trade unionists to regard UBI as a legitimate policy
alternative. Third, trade unions’ attachment to the work ethic and the insurance principle affects their
preferences for unconditionality and universality in policy settings. Fourth, their role in the industrial
landscape, and their degree of organisational inclusivity, have a strong influence on UBI support.
