A SECURITY contractor used by the Science and Natural History museums has been threatened with a private prosecution over alleged strike-breaking regulations.

The United Voices of the World (UVW) union said today that it was preparing legal action against contractor Wilson James, along with the BMSL agency.

UVW, whose members were due to walk out from today to Saturday, during the school half-term break, and from October 30 to November 1, has instructed the Public Interest Law Centre (PILC) to put the firms on notice of what would be the first prosecution related to the ban on the use of agency workers to break a strike.
