London, UK. June 21th, 2016. Rob Williams of the National Shiop Stewards Network speaks at the rally on the 10th day of their strike against sackings and low pay. Managed by CBRE, the offices are mainly let to Schroders and J P Morgan and cleaners are employed there by anti-union cleaning contractor Thames Cleaning. Thames spent over £20,000 trying to get an injunction to stop the strike, but failed though the union was hit by strict conditions and crippling legal costs. Credit: Peter Marshall/Alamy Live News
