Yes / This article examines the frequency, nature and outcomes of employers seeking injunctions against strikes and industrial action mounted by unions between 2005 and 2014.

Comparative analysis with Ireland highlights the specificity of the nature of British legal regulation of employer seeking injunctive relief.
