Around half of the membership of the TUC belongs to unions affiliated to the Labour Party (although the TUC itself is not affiliated) and Labour’s defeats in 2010 and 2015 meant union priorities such as those put forward by the TUC were not secured.
Približno polovica sindikatov, včlanjenih v TUC, je pridružena Laburistični stranki (čeprav ji sam TUC ni pridružen). Zaradi porazov Laburistične stranke v letih 2010 in 2015 izpolnjevanje prednostnih nalog sindikatov, kot jih je predložil TUC, ni bilo zagotovljeno.
