WORKERS at a major London NHS trust have overwhelmingly voted for industrial action over pay and staffing levels, their union Unite announced today.

Hundreds of cleaners, caterers, porters, security guards, ward hosts and domestic staff across the Barts Health NHS Trust backed walkouts by a whopping 95 per cent margin, the health union said.

Last year, Unite secured a landmark agreement that transferred 1,800 of the workers previously outsourced to contractor Serco to direct health service employment.
