This paper examines the rhetorical strategies employed in arguments both ‘for’ and ‘against’ national minimum wages. The issues are explored quite specifically in the UK context with reference to the hospitality industry. A key aspect of debates about the merits of a national minimum wage derive from economic studies which for the most part demonstrate either a positive or negative effect to a national minimum wage. The general lack of consensus of these studies has not prevented the deployment of research findings in the rhetorical strategies of non-economists engaged in lobbying for or against a national minimum wage. Illustrating this point with reference to the UK hospitality industry context, it is argued that like the cumulative evidence of economic research, such strategies are flawed, making moral predispositions rather than rational choices the only basis on which to predicate arguments about the desirability or otherwise of a national minimum wage.
