Trade Union Search Trees
WageIndicator has developed a large database of trade unions operating in its survey countries, providing a valuable resource for those seeking information about unions in a wide range of countries.
The WageIndicator survey includes a question ‘Are you currently a member of a trade union’. If ticked ‘Yes’, a follow-up question asks: ‘Of which trade union are you a member?’.
To facilitate responses, a ‘search tree’ listing the names of major unions has been developed for each survey country. These search trees generally consist of two levels – respondents first select from a list of the main union confederations in the country, and, having done so, are then asked to select from a list of unions which are affiliated to that confederation. Trade unions which are unaffiliated to a confederation may be listed under a first level group of ‘independent’ unions, or can be presented along with the confederations as stand-alone options. In countries where confederations may be less recognisable, the search tree consists of a straightforward one-level alphabetical list of the main unions in that country.
The content of the trade union search trees has been developed by the WageIndicator research team in consultation with local experts. Firstly, the information publicly available from unions, government authorities and other sources has been scrutinised to determine which major unions are most significant in terms of membership size or strategic importance. The conclusions drawn from this initial analysis have then been discussed with the local WageIndicator team. The final result is an effective overview of trade union organisations in each survey country.
As such, the WageIndicator trade union search trees presented here constitute a unique resource, providing a single access point for details of numerous trade unions organisations around the world.
