Honestly, unless one is a healthcare or some other type of "emergency" worker, YHWH's Sabbaths are not negotiable - especially the "High Holy Days"/Feasts. The thing is, as hard as it is in our Torah-less society, while your workers might not be Torah observant, YOU are, and it's YOUR business, so you shouldn't "cause anyone to work."
It’s the same reasoning behind why we aren’t allowed to commit commerce on a Shabbat. YHWH commanded His people to REST from “the worldly activities.” If we go to the movies or a restaurant on Shabbat, we are, in effect not only committing commerce, but causing the money and ticket taker and the cooks and waiters to work “for us” at that point in time.
Same thing with your business/company. Don’t work or cause your employees to work - unless you’re providing medical or some kind of other emergency services. RESTING on Shabbat is not a suggestion; it is a COMMAND.
Scripture tells us we are not even to allow our animals to work on Shabbats:
Exodus 20: 8 "Remember the day, Shabbat, to set it apart for God. 9 You have six days to labor and do all your work, 10 but the seventh day is a Shabbat for ADONAI your God. On it, you are not to do any kind of work -not you, your son or your daughter, not your male or female slave, not your livestock, and not the foreigner staying with you inside the gates to your property. 11 For in six days, ADONAI made heaven and earth, the sea and everything in them; but on the seventh day he rested. This is why ADONAI blessed the day, Shabbat, and separated it for himself.
Exodus 31: 13 "Speak also to the children of Israel, saying: 'Surely My Sabbaths you shall keep, for it is a sign between Me and you throughout your generations, that you may know that I am the Lord who sanctifies you."
Exodus 31: 16 "Therefore the children of Israel shall keep the Sabbath, to observe the Sabbath throughout their generations as a perpetual covenant. 17 It is a sign between Me and the children of Israel forever; for in six days the Lord made the heavens and the earth, and on the seventh day He rested and was refreshed.'"
Jeremiah 17: 21 Here is what ADONAI says: "If you value your lives, don't carry anything on Shabbat or bring it in through the gates of Yerushalayim; 22 don't carry anything out of your houses on Shabbat; and don't do any work. Instead, make Shabbat a holy day. I ordered your ancestors to do this, 23 but they neither listened nor paid attention; rather, they stiffened their necks, so that they wouldn't have to hear or receive instruction. 24 However, if you will pay careful heed to me," says ADONAI "and carry nothing through the gates of this city on Shabbat, but instead make Shabbat a day which is holy and not for doing work;
Nehemiah 13: 19 So when the gates of Yerushalayim began to grow dark before Shabbat, I ordered that the doors be shut; and I ordered that they not be reopened until after Shabbat. I put some of my servants in charge of the gates, to see to it that no loads be brought in on Shabbat. 20 The merchants and sellers of all kinds of goods spent the night outside Yerushalayim once or twice, 21 until I warned them, "Why are you spending the night by the wall? Do it again, and I'll use force against you!" From then on they stopped coming on Shabbat. 22 Then I ordered the L'vi'im to purify themselves and come and guard the gates, in order to keep the day of Shabbat holy. My God, remember this too for me, and have mercy on me in keeping with the greatness of your grace!
Isaiah 58: 13 If you hold back your foot on Shabbat from pursuing your own interests on my holy day; if you call Shabbat a delight, ADONAI'S holy day, worth honoring; then honor it by not doing your usual things or pursuing your interests or speaking about them. If you do, you will find delight in ADONAI - I will make you ride on the heights of the land and feed you with the heritage of your ancestor Ya'akov, for the mouth of ADONAI has spoken."
