A group of employees at the Briarwood Furniture Co.'s manufacturing plant were interested in joining a union. The Briarwood Furniture Co., employs 400 unskilled workers and 100 skilled workers in its plant. The unskilled workers operate the industrial machinery used in processing Briarwood's line of standardized plastic office furniture. The skilled workers, who work in an entirely separate part of the plant, are experienced artisans who craft Briarwood's line of expensive wood furniture products. Do you see any problems with a single union's representing all the workers at the Briarwood plant? Explain.
