Apprentices under the UA Local 343 agreement are paid a graduated percentage of the journeyman rate, typically starting near 40–50% in the first period and stepping up each six-month or annual period until reaching 100% at turnout. Against the current $58.24/hour journeyman rate, a first-period apprentice would be in the $26.21–$29.12/hour range. The exact percentage schedule is set by the local's JATC.
UA Local 343 is headquartered in Vallejo-Napa, CA and dispatches plumbers & pipefitters manpower throughout its chartered jurisdiction. Work performed inside that territory falls under the local's collective bargaining agreement and wage schedule, even when the contractor is based elsewhere and travels in.
Most locals require applicants to be at least 18, legally able to work in the U.S., hold a high school diploma or GED, pass a basic math/aptitude assessment and a drug screen, and be physically able to perform plumbers & pipefitters work. Some Local 343 programs give preference to applicants inside the jurisdiction or to veterans. Eligibility rules are set by the local's Joint Apprenticeship and Training Committee (JATC), so confirm the current criteria with the hall before applying.
Apprenticeship applications go through the UA Local 343 JATC, not through a contractor or a recruiter. Applications typically open in defined intake windows each year: you submit the application with proof of age, education, and residency, sit for an aptitude test, and then interview. Ranked applicants are placed on an eligibility list and indentured as signatory contractors call for apprentices. Gulfstream Strategic Placements does not process apprenticeship applications — contact the Local 343 training center directly.
Plumbers & Pipefitters apprenticeships generally run four to five years — roughly 8,000–10,000 hours of on-the-job training plus several hundred classroom hours per year. Apprentices earn a paycheck the entire time, stepping up through the wage periods until they turn out as journeymen at 100% of scale.
Signatory contractors hire through the local's hiring hall, so working under the UA Local 343 agreement generally means being a member or being organized in through the local's process. Journeymen from other locals can travel in by signing the out-of-work book, subject to the local's referral rules and manpower needs. Non-union plumbers & pipefitters professionals are usually placed with open-shop contractors instead — we recruit for both.
Rates move with the collective bargaining agreement, typically on a fixed anniversary date each year of a three- to five-year contract, with negotiated increases split between the base wage and the fringe package.
