“…Research on unions in Western Europe between the 1960s and 1990s also suggested that unions preferred restrictive immigration policies and focused on protecting the interests of their national members (Penninx and Roosblad, 2002). However, more recent empirical studies, beginning in the 1990s, show that union organizations are, in fact, becoming more inclusionary (Avci and McDonald, 2000;Freeman, 1995). In addition, there is now a very rich, mostly qualitative, body of literature which has documented the very considerable inclusionary efforts of certain unions -especially in the United States and to a lesser extent in Britain and elsewhere in Europe -to recruit immigrant workers as a means of boosting their memberships and halting long-term organizational decline (Holgate, 2005;Milkman, 2006;Ness, 2005;Trades Union Congress (TUC), 2003).…”
