A project of Local 343 of the United Brotherhood of Carpenters and Joiners of America and the Construction Labour Relations Association (CLRA) of Manitoba documented the workplace literacy skills needed by union carpenters on job sites in Manitoba. The following techniques were used: mailed questionnaires to the carpenter members of Local 343 and to employer members of CLRA Manitoba, individual and group interviews, and onsite observations. The workplace literacy skills identified during the project were grouped into those needed by carpenters and those needed by supervisory-level carpenters. Although certain reading and writing skills were needed by all levels of carpenters, the amount of time spent on performing these skills increased proportionately as supervisory responsibilities increased. A similar increase was noted for math skills. Reading skills were grouped into safety, layout, administrative, and other. Computation skills were classed as follows: whole number, fraction, and decimal operations; workplace basics; layout; applied geometry; math-based tools; and other. Communication skills were grouped into written, verbal, nonverbal, and employability skills. Workplace literacy skills needed by supervisory-level carpenters fell into two categories: reading and communications. A table was constructed that identified critical, essential, and important workplace skills. Recommendations were made for two areas: courses and actions by Local 343 and CLRA. (Appendixes include the questionnaire, interview instrument, and employer survey.) (YLB)
