Basis of authority
https://www.osha.gov/laws-regs/regulations/standardnumber/1975/1975.2

The power of Congress to regulate employment conditions under the Williams-Steiger Occupational Safety and Health Act of 1970, is derived mainly from the Commerce Clause of the Constitution. (Sec. 2(b), Public Law 91-596; U.S. Constitution, Art. I, Sec. 8, Cl. 3; "United States v. Darby," 312 U.S. 100.) The reach of the Commerce Clause extends beyond Federal regulation of the channels and instrumentalities of interstate commerce so as to empower Congress to regulate conditions or activities which affect commerce even though the activity or condition may itself not be commerce and may be purely intrastate in character. ("Gibbons v. Ogden," 9 Wheat. 1, 195; "United States v. Darby," supra; "Wickard v. Filburn, 317 U.S. 111, 117; and "Perez v. United States," 91 S. Ct. 1357 (1971).)

2. Seems like slightly firmer ground than the CDC order

but probably not enough firmer to stand up in court for long.

Still... if a few million extra people get jabbed before the order is blocked... it could have significant positive impact.
