Congress is the policy making body of the TUC, and meets 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.

In a change this year Congress opened with an early evening session on Sunday 9 September, which ran from 4pm - 7pm. Congress then met from 9.30am - 5.30pm on Monday 10 September and Tuesday 11 September. It then met from 9.30am on Wednesday 12 September and concluded by 4pm that day.
