Might give 'em a bit of time to do a version 1.01 on that order. . . .
OK, I just read that order and the very long list of "life sustaining businesses." Took a minute to find both the exact order (very short) and the very long list of exempted businesses.
Any small shop owner that can't figure how they comply is too dim to stay in business, IMO. Don't complain, don't listen to others or the news complaining. Read the order.
First, anyone in any business can do virtual work or telecommute. As I read it, any sole proprietor can declare his workplace a telework node, show up at work, close the door, and stay late as they want. Phone your customers, your wife, whatever.
Second, businesses that normally have people cheek to jowl (like crowded restaurants) can do take-out as long as they practice comparative isolation (6' apart, wiping down shared surfaces, etc.). You now have a take-out job shop?
Third, there's a very long list of essential manufacturing businesses that can stay open, as long as they protect their workers. I'd be surprised if anyone here (and as noted above for metal manufacturing) wouldn't find they are all of a sudden a "life sustaining" business. Tell your kids. If you happen to make stuff out of steel or aluminum you're in. If your customers are in the food, paper, chemical, plastics, etc. industries you're good. Some of the stuff, like distingushing non-ferrous materials as non-essential while aluminum as essential is stupid. Likely steel & aluminum have lobbyists, while poor old brass, copper, and inconel are left to their own devices. The list is here:
