Mishnah 1א׳

הַשּׂוֹכֵר אֶת הַפּוֹעֲלִים וְאָמַר לָהֶם לְהַשְׁכִּים וּלְהַעֲרִיב, מְקוֹם שֶׁנָּהֲגוּ שֶׁלֹּא לְהַשְׁכִּים וְשֶׁלֹּא לְהַעֲרִיב, אֵינוֹ רַשַּׁאי לְכוֹפָן. מְקוֹם שֶׁנָּהֲגוּ לָזוּן, יָזוּן. לְסַפֵּק בִּמְתִיקָה, יְסַפֵּק. הַכֹּל כְּמִנְהַג הַמְּדִינָה. מַעֲשֶׂה בְּרַבִּי יוֹחָנָן בֶּן מַתְיָא שֶׁאָמַר לִבְנוֹ, צֵא שְׂכֹר לָנוּ פוֹעֲלִים. הָלַךְ וּפָסַק לָהֶם מְזוֹנוֹת. וּכְשֶׁבָּא אֵצֶל אָבִיו, אָמַר לוֹ, בְּנִי, אֲפִלּוּ אִם אַתָּה עוֹשֶׂה לָהֶם כִּסְעֻדַּת שְׁלֹמֹה בִשְׁעָתוֹ, לֹא יָצָאתָ יְדֵי חוֹבָתְךָ עִמָּהֶן, שֶׁהֵן בְּנֵי אַבְרָהָם יִצְחָק וְיַעֲקֹב. אֶלָּא עַד שֶׁלֹּא יַתְחִילוּ בַמְּלָאכָה צֵא וֶאֱמֹר לָהֶם, עַל מְנָת שֶׁאֵין לָכֶם עָלַי אֶלָּא פַת וְקִטְנִית בִּלְבַד. רַבָּן שִׁמְעוֹן בֶּן גַּמְלִיאֵל אוֹמֵר, לֹא הָיָה צָרִיךְ לוֹמַר, הַכֹּל כְּמִנְהַג הַמְּדִינָה:

[If] one hires laborers, and then told them to begin work early and work late: in a place where they are accustomed to not begin work early and work late, he is not permitted to force them. In a place where they are accustomed to feed [workers], he should feed [them]; to provide sweets, he must supply. Everything goes according to local custom. It once happened that Rabbi Yochanan ben Matya said to his son, "Go out and hire laborers for us ." He went and committed to providing them with food. And when he came to his father, he said to him, "My son, even if you made for them a meal as [befitting] Solomon in his time, you would not have fulfilled your obligation toward them, for they are children of Avraham, Yitzhak, and Ya'akov. Rather, before they begin labor, go and say to them, '… on the condition that the only [claim] you have on me is for bread and beans.'” Rabban Shimon ben Gamliel says: It is not necessary to say so, [since] everything goes according to local custom.

Mishnah 2ב׳

וְאֵלּוּ אוֹכְלִין מִן הַתּוֹרָה. הָעוֹשֶׂה בִמְחֻבָּר לַקַּרְקַע, בִּשְׁעַת גְּמַר מְלָאכָה, וּבְתָלוּשׁ מִן הַקַּרְקַע, עַד שֶׁלֹּא נִגְמְרָה מְלַאכְתּוֹ, בְּדָבָר שֶׁגִּדּוּלוֹ מִן הָאָרֶץ. וְאֵלּוּ שֶׁאֵין אוֹכְלִין. הָעוֹשֶׂה בִמְחֻבָּר לַקַּרְקַע בְּשָׁעָה שֶׁאֵין גְּמַר מְלָאכָה, וּבְתָלוּשׁ מִן הַקַּרְקַע מֵאַחַר שֶׁנִּגְמְרָה מְלַאכְתּוֹ, וּבְדָבָר שֶׁאֵין גִּדּוּלוֹ מִן הָאָרֶץ:

And these may eat, according to the Torah: The one who works with what is attached to the ground when the labor finished; and with what is detached from the ground [even] before its work is completed – if it is something that grows from the ground. And these do not eat: the one who works with what is attached to the ground at a time when the labor is not finished, and [works with] what is detached from the ground after its labor has been finished, and [one who works with] something that does not grow from the ground.
