The Lad’s favourite answer to this question is the Unions Union Confederation, a body which represents some 250,000 trade union members.
The Confederation was established in 1990, after the collapse of the communist bloc, and has a membership of some 5 million members.
Unions are now recognised by many governments and unions in the EU and North America.
Unite, the largest union, has about 5 million member members, including about 2 million from the US.
Unison has been a staunch critic of the government, and recently took over the umbrella trade union of the British Airways staff.
Unist’ot’en, the second largest union and one of the largest in the UK, has 3 million members and a membership totalling over 7 million.
The National Union of Journalists, which represents more than 1 million journalists and the news media in the United States, is another notable member of Unison, as is the British Film and Television Guild.
A number of other unions have joined the campaign against Brexit.
Unites and Friends, which campaigns for better working conditions for journalists and has some 4 million members, has also joined the UK Independence Party’s campaign.
Uncut, the campaign to keep the NHS free at all times, has been active on the internet, with about 2.2 million members across Europe.
But Unions unionists are divided on whether the EU is the best option.
David Walker, of the Trade Unionists and Unions Alliance, said: ‘There is a real need for trade unions to come out of the shadows and be more visible to members of the public and political parties.’
We know the Conservatives are the biggest party, and they have the best interests of working people at heart.’
They will always find ways to keep them in power, so there is a need for the union movement to be more influential and political in the long term.’
It is time for unions to start speaking up on the front of the campaign and get involved.
They are key to the future of the UK.’
Unions have a real responsibility to keep members of our community safe, but they also have a moral obligation to take the fight to the Tories.’
The EU is already the biggest obstacle to jobs, security and social cohesion, so they will always be in the lead for this fight.’
That means it is important that we take a stand and fight for the rights of all workers in the union.
‘We need to have a genuine debate on this issue and the impact it has on our lives.
‘We need a Labour government that fights for workers, not just union members, but all working people, so that they are not stuck in a cycle of austerity.’
