In many cases (though not all!), when workers are striking against a retail business, they want the customers to keep coming. Showing the strain that gets put on the system in such cases can be part of the leverage the union exerts.
This is why we, on the outside, need to listen to what the union is asking of us, and not just loudly announce that we are boycotting in solidarity, or "refusing to cross the picket line", if that's the opposite of what they want.
Or don't! It's fine to be pro-labor but for your interests not to intersect with every strike. One might have a different opinion about the moral weight of an NYT strike versus that of the Marriott hotel housekeeping staff, for instance. You might personally find yourself morally aligned with every strike, and in that case you should pay attention to what the strikers are asking. Or you might not. Things are complicated!
Either way: it is not in fact a given that customers are obliged by solidarity to boycott businesses dealing with strikes.
