Union coalitions and strategic framing: The case of the Agricultural Advisory Panel for Wales

This article analyses the creation of a union coalition that introduced a new employment relations institution: the Agricultural Advisory Panel for Wales. Building on social movement theory, the article argues that the union’s strategic framing within a conducive political opportunity structure enabled the coalition to form and pursue its goals. The union engaged in a specific frame alignment strategy, frame bridging, to explore and mobilize intersections and shared interests between its own frame and those of its coalition partners. Frame bridging prompted actors to reverse their policy preferences and participate in the coalition, which was facilitated by a political opportunity structure formed from the political salience of the agricultural sector and pre-existing social ties in the ‘small state’ political economy of Wales. The article contributes to the literature by developing and extending the frame bridging concept as a process enabling union coalitions.
