Is it permissible to continue working in a factory whose production has shifted from soft drink cans to alcoholic beverage cans, given the absence of an alternative job and the presence of a large family dependent on this work?

It is not permissible to continue working in a factory that bottles alcoholic beverages, except in cases of dire necessity, which ceases once the necessity is gone. Necessity is defined as a person reaching a point where, if they do not commit the prohibited act, they will perish or be close to perishing, or fall into hardship that is difficult to bear.
