In a locale where employers are accustomed to feeding their laborers, the employer must feed them. If they are in a locale where an employer is accustomed to providing their laborers with sweet foods, he must provide such food.
There was an incident involving Rabbi Yoḥanan ben Matya, who said to his son: Go out and hire laborers for us. His son went, hired them, and pledged to provide sustenance for them as a term of their employment, without specifying the details. And when he came back to his father and reported what he had done, Rabbi Yoḥanan ben Matya said to him: My son, even if you were to prepare a feast for them like that of King Solomon in his time, you would not have fulfilled your obligation to them, as they are the descendants of Abraham, Isaac, and Jacob. Rather, before they begin engaging in their labor, go out and say to them: The stipulation that food will be provided is on the condition that you have the right to claim from me only a meal of bread and legumes, which is the typical meal given to laborers.
