Certification granted for plumbers and steamfitters; welders excluded from bargaining unit unless qualified in trade.
The applicant trade union applied for certification as the bargaining agent for plumbers and steamfitters employed by the respondent in the construction industry.
The applicant requested a clarity note to include welders working in these trades in the bargaining unit.
The Board held that because plumbing and steamfitting are compulsory certified trades under the Apprenticeship and Tradesmen's Qualification Act, only qualified journeymen or apprentices can lawfully work in those trades and be included in the bargaining unit.
The request for a clarity note regarding welders was denied, but the Board granted the application for certification for the qualified tradespersons.
