UCU operates a political fund which expressly
does not contribute to any political party, but is used for campaigning and lobbying to promote the interests of UCU members. The contribution level is one percent of the national subscription rate. Members may opt in to the fund.
If you choose not to contribute to the political fund you shall not be excluded from any benefits of the union or placed in any respect, either directly or indirectly, under a disability or at a disadvantage as compared to other members of the union.
