 Following growing disputes over the running and financing of the club , in June 1900 Thames Ironworks F.C. was disbanded , then almost immediately relaunched on 5 July 1900 as West Ham United F.C. with Syd King as their manager and future manager Charlie Paynter as his assistant . Because of the original " works team " roots and links ( still represented upon the club badge ) , they are still known as " the Irons " or " the Hammers " amongst fans and the media .
