The Trades Union Congress (TUC) is a federation representing the majority of UK unions.
As an affiliate PCS takes part in the policy-making body of the TUC - the annual congress - which meets for four days each year during September.
Each affiliated union can send delegates to congress - the larger the union, the more it can send. At congress 'motions' (resolutions for debate) are proposed and discussed. These form the basis of the TUC's work for the next year.
