Commentary for Avodah Zarah 126:13

The Jew is hired to break the jugs, which would end in the destruction of the wine inside. But until that point, he wants the jugs to continue to exist. Are his wages prohibited because he does want the caskets to continue to exist at least until he breaks them? Or are they permitted because ultimately he is causing the wine’s destruction? Nahman allows the Jew to do this work.

The Talmud cites a baraita concerning working in a field with mixed seeds. A Jew may not work such a field with a non-Jew but he may work together to uproot them, because ultimately this is uprooting what is improper. So too, a Jew may work with a non-Jew to break casks of yayin nesekh.
