After World War II, the Savoy Group experienced a strike of its employees in support of a waiter dismissed from the hotel. The matter was judged so serious that the government set up a court of inquiry. Nevertheless, the hotel continued to attract celebrities. In 1946, Wontner set up "The Savoy Management Scheme", a school to train hoteliers, that was maintained for half a century. The last major appointments of Rupert D'Oyly Carte's chairmanship were Wyllie Adolf Hofflin, general manager from 1941 to 1960, and August Laplanche, head chef from 1946 to 1965. When Carte died in 1948, his daughter Bridget did not wish to become chairman, accepting instead the vice-chairman position, and the Savoy board elected Wontner, the first person to combine the roles of chairman and managing director since the Savoy's founder, Richard D'Oyly Carte. Wontner remained managing director until 1979 and chairman until 1984, and he was president thereafter until 1992.
