The workers at an Amazon warehouse on Staten Island New York voted for collective bargaining representation with the Amazon Labor Union (ALU) in an election held in March 2022. The NLRB issued a certification of the union's exclusive representative status for all warehouse employees at the Staten Island facility.

The ALU seeks to escalate the labor dispute further by asking suppliers of Amazon not to sell their products through Amazon and by asking customers of those suppliers not to buy the supplier's products on Amazon. The ALU asks you whether it would be more advisable to patrol with pickets in front of the suppliers' premises or to distribute a leaflet conveying the same message as would appear on the picket signs. How would you answer them? Explain your answer.
