Since October 2017, Jon Preciado has served as the Business Manager of the Southern California District Council of Laborers.
Preciado began his career in the Labor Movement in 1986 and has worked for several unions, including the Cement Masons and Operating Engineers (Stationary) Local 501. He has been a compliance representative investigating unscrupulous contractors on public works, an organizer in both the private and public sectors, a Field Representative, and a Chief Negotiator. To broaden his experience, Jon accepted a position in January 1995 with the AGC of California and served as the Director of Industrial Relations. He believes it gave him a unique glimpse into the daily challenges union contractors face from their non-union competition and sometimes from the trades to which they are signatories. In 1998, Jon left AGC to become Executive Director of Audit and Collections for the Construction Laborers Trust Funds for Southern California. In mid-2000, Preciado began a new challenge by the Laborers International Union of North America (LiUNA!) and Laborers Local 1184. It was to represent the Hod Carriers (Plaster Tenders) in the (12) Southern California counties after LiUNA! consolidated all Plaster Tenders under Local 1184. Under his leadership, a new apprenticeship program experienced much success, turning out qualified journeymen that replaced (and continue to replace) an aging plaster tender workforce while maintaining the highest retention rate of all the apprenticeship programs in the wall and ceiling industry.
Jon is Chairman/Co-Chairman of the Laborers Health & Welfare Trust, the Laborers Pension Trust, the Laborers Joint Apprenticeship Committee and Training Trust, the Laborers Vacation Trust, the Plaster Tenders Joint Apprenticeship Committee and Training Trust, the Center for Contract Compliance as well as several committees of all these Trusts.
