PSOOL welcomes affiliation from trade union branches. Several of the officers who deceived women into intimate relationships became members of trade unions which they spied on.
The Metropolitan Police has admitted there was collusion between these Special Branch units and the Economic League / Consulting Association. Information about trade union activists was passed to private construction companies such as Skanska and McAlpine in order for them to blacklist workers.
The spycops scandal goes to the heart of the trade union movement.
