Please answer these following questions that are listed below. Note please do not go on a long tangent giving me unnessicary useless information that has nothing to do with the question. Please just answer the question in a direct clear format Thank you.

1. Unions often represent many different types of workers doing different types of work within the same workplace or bargaining unit. How should unions determine bargaining priorities while also meeting the expectation that they represent the interests of all their members?
2. What kind of evidence might indicate a union decision that is arbitrary? A decision that is discriminatory? A decision that is in bad faith?
3. How much should external information, such as salary rates at comparable workplaces, be used in the collective bargaining process?
