(יח) רַבָּן שִׁמְעוֹן בֶּן גַּמְלִיאֵל אוֹמֵר, עַל שְׁלשָׁה דְבָרִים הָעוֹלָם עוֹמֵד, עַל הַדִּין וְעַל הָאֱמֶת וְעַל הַשָּׁלוֹם, שֶׁנֶּאֱמַר (זכריה ח) אֱמֶת וּמִשְׁפַּט שָׁלוֹם שִׁפְטוּ בְּשַׁעֲרֵיכֶם:
(18) Rabban Shimon ben Gamaliel used to say: on three things does the world stand: On justice, on truth and on peace, as it is said: “execute the judgment of truth and peace in your gates” (Zechariah 8:16).
2. Treat your employees fairly.
One of the most difficult parts of running a business is dealing with employee issues. Employees can be demanding: raises, time off, expenses, conflicts and more. When confronted with these issues, I just thought about the principle of paying employees on time: “The wages of a worker shall not remain with you all night until the morning” (Lev 19:13). The Torah also commands us not to take advantage of your employees: “You shall not abuse a needy and destitute laborer, whether a fellow countryman or a stranger” (Deut, 24:14). This taught me to always treat employees equally and fairly. I applied an absolute level of fairness among all our employees when it came to pay and all other issues. Race, age, gender, religion, color – these had no bearing. It is always difficult to say no, but when you develop a reputation for fairness to your employees, they respect you more and know that they were treated properly.
6. Build a reputation for integrity and honesty.
The Talmud discusses the questions one is asked in the heavenly court at the end of one’s life (Shabbat 31a). The first question asked is: Were you honest in your business dealings? This is the first question because it’s the true measure of one’s success in life. There is no greater temptation to cheat than is a business setting where one can earn more profits. If you can overcome this great temptation, you will reach a high level of character that others esteem. Your customers, employees and those you do business with want to patronize your business. When you are honest, your business grows. You also have the right answer in the heavenly court. As the Medrash says, “If one is honest in his business dealings and people esteem him, it is accounted to him as though he had fulfilled the whole Torah” (Mechilta B’Shalach 1).
