USPS will get this order and SHRUG. They will do what they always do and simply laugh at the judge’s order.
They couldn't do anything this late in the game if they wanted too, I worked for the USPS for two years, the bureaucracy is worse than even the DMV because everything also has to go through the union. Mail delivery schedules for the next couple weeks have already been made, they attempt to change them and call extra mail carriers in, they will have grievances flying left and right, either that or those called in will just take a sick day.
