business advocates were concerned that a bill that was barely debated by the opposition in the legislature in the bill's first stages would give power to labour unions, and they held up passage of the bill by several weeks. the bill combined the activities of six boards into one unified labour board and created a labour management review committee that consisted of managers and employees from unionized workplaces. critics wanted non-unionized business people to have a say in how workplaces become unionized and worried about a preamble that supported including collective bargaining as part of the freedom to assemble, while advocates argued that the committee was required by law to consult with businesses and that the preamble had been in the canada labour code since 1972. the government amended the bill to guarantee non-unionized businesses are consulted on potential labour changes affecting matters including union drives.
