To take part in political activity unions have to maintain a separate political fund.
In UNISON you can choose to opt-in and pay an additional 5 per cent contribution on top of your subscription to either the Labour Link or the Campaign Fund. You can also opt-in to contribute to both..
The Campaign Fund (previously the GPF) is not affiliated to any political party. The money you pay into the fund is used to support local campaigns, to give a boost to the union’s national political campaigns and pay for political advertising.
The LabourLink Labour Link works directly within the Labour Party to take UNISON’s policies into the heart of the party.
Members individually choose which fund to contribute to. They can also decide to opt out of any political levy or contribute to both funds
