Branches are in turn allocated to divisions - there are 14 geographical divisions, plus one for London Transport. Each division has a Divisional Council which meets at least twice a year, and members in each division elect a member of the Executive Committee (EC). EC members are elected for a three-year term, subject to a maximum of two consecutive terms of office (but can stand again after 3 years off the committee). The Executive Committee meets approximately ten times a year in London and continuously during the four-day annual conference held each May. The EC is responsible for the efficient running of the union, the employment of staff (of whom there are about 70), the oversight of the union's finances, and the implementation of decisions of Annual Conference.
