Nigel Farage has invited Britain’s trade unions to break their historic link with the Labour Party and affiliate with Reform UK instead, a move swiftly rejected by union leaders who called him “no friend of the workers”. The snub came after a poll suggested Farage was the most popular party leader among trade union members, stirring a debate about what unions stand for and who they represent.
Trade unions are organisations that represent workers in negotiations with employers over pay, conditions, and rights. In the UK, 48 unions are affiliated with the Trades Union Congress (TUC), the largest federation of workers. Eleven of these unions are officially linked to the Labour Party, representing around four million workers. That link is both financial and political: union members can vote in Labour leadership contests, union representatives sit on Labour’s National Executive Committee, and unions donate millions to the party. In the first three months of this year, Labour received £1.4m from seven unions, including £392,544 from Unite and £366,936 from Unison.
“An evergreen explainer on trade unions' role in UK politics, their Labour links, and the Reform UK challenge.”
The relationship dates back to Labour’s founding in 1900, when unions created a political party to fight for working-class interests in Parliament. For decades, that bond was mutually beneficial: Labour pursued pro-worker policies, and unions provided money, volunteers, and votes. But tensions have grown under the current Labour government, which some unions say has not gone far enough on workers’ rights. Unite general secretary Sharon Graham, while rejecting Farage’s offer, also criticised Labour for “dithering”. The TUC has now called on the government to impose an “emergency social tariff” on energy bills, which would give lower-income households a 30% discount (worth £559 a year) and middle-income families a 20% cut (£373), paid for by a windfall tax on banks. The TUC says the scheme could save 65% of UK households money and reduce inflation by 0.3 to 0.4 percentage points.
For UK readers, this matters because unions remain a powerful voice for workers, shaping policies on sick pay, unfair dismissal, and energy costs. Reform UK has pledged to scrap Labour’s Employment Rights Act, which gives workers sick pay from day one and the right to claim unfair dismissal after six months. Unions see that as a direct threat. The TUC’s Paul Nowak dismissed Farage’s claim to be the “party of the workers” as “laughable”, while Unison’s Andrea Egan called it “a con”. The outcome of this battle will affect millions of workers’ pay packets, job security, and household bills.
Q: Why do trade unions support the Labour Party? Trade unions founded the Labour Party in 1900 to represent working-class interests in Parliament. They provide funding and political backing, and in return, Labour typically supports pro-worker legislation. Union members also have a vote in Labour leadership elections.
Q: What is the TUC’s proposed “social tariff” on energy bills? The TUC wants the government to give households a discount based on income, ranging from a 30% cut for low-income households (saving £559 a year) to 10% for middle-income households (£186). The scheme would cost £3.4-5.9bn per year, paid for by a windfall tax on banks. It would help 65% of UK households and reduce inflation.
Q: How much money do unions give to Labour? In the first three months of this year, seven unions donated a total of £1.4m to Labour. Unite donated £392,544 and Unison gave £366,936. Unions also give a portion of membership fees to the party via political funds.
What happens next? Reform UK has invited unions to its party conference in September, but all major union leaders have refused. The TUC is urging Labour to adopt its energy bill plan, and the government faces pressure to prove it is on the side of workers. Meanwhile, internal union disputes, such as a row between the NEU teachers’ union and Unite, Unison, and GMB over organising teaching assistants, threaten to weaken the movement further. The coming months will test whether the union-Labour alliance can hold, or if Reform UK can make inroads.
