The Operative Plasterers and Allied Trades Society of Ireland (OPATSI) is a trade union representing plasterers and allied trades such as Tilers, Slaters, Metal Stud Fixers and Ceiling fixers in Ireland. The union was founded in 1893 as the Regular Stucco Plasterers' Trade Union of the City of Dublin. In its early years, it met at the Trades Hall on Capel Street in Dublin, and was led by Harry Murtagh and James O'Neill.[1][2] From its early days, the union has claimed to have descended from St Bartholomew Guild of Plasterers and Bricklayers which, it claims, was founded in 1670.[2] Gerard Doyle became secretary of the union in 1928, and under his leadership it was renamed as the Operative Plasterers Society. Leo Crawford became president in 1938, and brought it to prominence within the Irish trade union movement. Under his leadership, the union was a founder of the Congress of Irish Unions. In the 1950s, its main rival, the British-based National Association of Operative Plasterers, decided to withdraw from Ireland, and its Irish members transferred to the Dublin-based union, which took the name "Operative Plasterers and Allied Trades Society of Ireland" to reflect its broader remit.[2] Today the union is based in Merrion Square, where a number of other Unions reside. The Union has remained an autonomous craft union and continues to defend the craft of Plastering vigorously considering the craft encapsulates many different disciplines. 2018 saw the Union celebrating 125 years representing craft workers. In more recent times, the union have embarked on a campaign to highlight the issue of bogus self employment in the construction sector. A number of cases have been referred to the Workplace Relations Commission. Plasterers have now been properly designated as employees in order to vindicate their rights as workers under law. Below are some decisions.[3][4][5] General Secretaries 1901: George Leahy 1912: Thomas Irwin 1928: Gerard Doyle 1973: James Irwin 1981: Richard Kearney 2010: Billy Wall Presidents 1938: Leo Crawford 1969: James Cheevers 1979: Eamonn Sinclair 1992: Jimmy Irwin 1999: Gerry Lumsden 2009: Sean Irwin 2019: Eugene Moloney 2020: Martin Murphy References Francis Devine, Fintan Lane and Niamh Puirséil, Essays in Irish labour history: a festschrift for Elizabeth and John W.
