A LONDON hospital was brought to a “standstill” today as unpaid agency workers made another challenge to ISS over their pay cycle changes.

The Star understands that a mass grievance of GMB members took place at Princess Royal Hospital in Orpington against the management of subcontracting giant ISS.

A source close to the workers told the Star that 22 workers attended the meeting, and that management tried to force some of the workers to return to work.

However, all of them refused to do so.

At the meeting, management were told that workers cannot afford to pay council tax, rent or even buy food due to ISS’s “pay harmonisation scheme,” which has left them going unpaid for up to three weeks.

At a grievance earlier this week in the Queen Elizabeth Hospital, Woolwich, workers told management that they were facing starvation as a result of the pay change.

GMB regional organiser Helen O’Connor told the Star: “ISS workers have had enough of being mistreated by this exploitative contractor and they are uniting and  organising to fight back.

“These staff work hard to keep our hospitals running and make sure patients are cared for.

“They are entitled to their full wages but these pay changes will impact them and their families for months.

“My union will take all steps necessary to stamp out the abuse of these vital hospital workers and in doing so we know we will be protecting NHS front-line services for future generations.”

ISS have been contacted by the Star for comment.
