Florence Amy "Flo" Cluff OAM, formerly Kershaw and Davis (4 November 1902 – 20 September 1990) was an Australian trade unionist, communist and pensioner activist.
She married labourer Robert Dawson Kershaw at Einasleigh on 29 November 1921; she moved to Brisbane in 1931 and was divorced in 1932.
She was one of the first women elected to the secretaryship of a union and radicalised the HCRU during her tenure, requiring larger hotels to provide female cooks with equal pay and instituting the five-day working week, sick leave and weekend penalty rates.
The HCRU was absorbed into the Federated Liquor & Allied Industries Employees' Union of Australia in 1961 and Davis became independent secretary.
[1] On 9 October 1975 Flo Davis married retired cleaner Eric James Richard Cluff; the newlyweds travelled around Australia before joining the Petersham branch of the Combined Pensioners' Association.
