state that British unions are more likely to employ the organizing model, rather than the serving model, if they are bigger and more open to influence from "other countries". According to Heery, Simms, Simpson, Delbridge, and Salmon, British unions are more likely to focus on the ideological basis for the organizing model, rather than the practical applications of it. Jack Fiorito states that the U.K.'s adaptation of the organizing model has some very specific characteristics that may or may not be seen in other countries. Fiorito lists "...less reliance on paid staff and much lower dues levels in U.K. unions..." as important features of the organizing model in the U.K. Fiorito did extensive research about the condition of British unions in the 2000s, which demonstrated that the organizing model was influential in British unions in the 2000s. When Fiorito interviewed U.K. union members during this timeframe, "Almost half of respondents (45%) volunteer that their union is adopting the OM," which is Fiorito's abbreviation for the organizing model. The organizing model was present in many British unions in the 2000s, and the workers were aware of its presence. The British union members largely felt that the organizing model was a good model to have implemented in their unions, and they were satisfied with its results. Fiorito states that "Although the OM varies somewhat in meaning, a strong majority of unionists feel that their union is truly committed to recruiting and organizing new members...". The Irish general union SIPTU established an Organizing Unit in 2004 and its president, Jack O'Connor, set as his objective the transformation of SIPTU – hitherto firmly committed to a servicing agenda – into an organizing union. SIPTU is also seeking to learn from the experience of the SEIU. It remains to be seen how (and whether) a commitment to the organizing model of trade unionism can be reconciled with the union's traditional support for national 'Social Partnership'. The Transport and General Workers Union (T&G) has begun to make some of the more serious moves of any of the larger British unions to learn from the SEIU's strategies – though some smaller unions (such as Community) have been applying the organizing model for some years. In 2005, the T&G launched a Justice for Cleaners campaign, which has been organizing workers in Canary Wharf, the Houses of Parliament, and, towards the end of the year, on the London Underground.
