Let your conscience guide you, but in my opinion you should look to the union to see what they are asking you to do. A boycott of a struck company is not necessarily what the union wants you to do. One can imagine, for instance, that consumers continue to demand a company's product, demand that strengthens the union's bargaining power. When in doubt you can always check the union's web site or social media to see what you can do to support them.
