CLEANERS for transnational banking juggernaut JP Morgan Chase were threatened with a legal injunction yesterday unless they promised to ignore all acts of solidarity at an upcoming all-out strike.

Staff at London’s 100 Wood Street — offices for JP Morgan, Schroder and Law Debenture investment banks — are currently balloting for strikes over job losses and living wage demands.

Two cleaners have already been dismissed by subcontractor Thames Cleaning and Support Services Ltd, a grievance their non-TUC affiliated union United Voices of the World (UVW) is hoping to take to a tribunal.
