By what authority???
He's the boss.
I wonder why not also mandate for all residents? Why just workers?
FWIW, I don't believe he has the authority, but most of government runs on authority it does not have.
By what authority???
***********
Rulers don’t need authority.
THEY are the authority.
No authority. Even this idiot President we have installed has people smart enough to tell him they don’t have the authority. That’s why they went the fascist route by intimidation and extortion of employers and threats with government agency revenge. De Blasio is operating on pure bluff and intimidation.
