GMB members who work as cleaners and caterers across South London and Maudsley NHS Trust have been taking industrial action this week, having already taken six days of action already this summer.

The members are employed by ISS and are taking action to win a proper pay rise.

This Wednesday, they are taking their dispute to parliament.

You can join them as they assemble at 10am in Trafalgar Square before marching past Downing Street and down to Parliament Square.
