A 61-year-old cleaner swept up more than $700,000 yesterday for a back injury suffered when she fell off a chair. Lam Pui-ying had been standing on tiptoe on a chair to clean a door when the accident happened. She is to receive $711,905 from her employers under an agreement struck at the Court of First Instance. Ms Lam claimed a shortage of ladders and the failure of her employers, Ramada Renaissance Hong Kong, to provide staff to help her had increased the risk of accident. She had previously injured her wrist at work and was only supposed to be on light duties. The injury to her back happened on July 13, 1993, as she was cleaning a door at the Ramada Renaissance Hong Kong hotel's Tang Palace restaurant. She suffered a compression fracture in her back, complained of pain for several years and had an operation on her spine. Deputy Judge Gareth Lugar-Mawson welcomed the agreement.
