On Wednesday, Union Pacific Corp said they will require all of its 31,000 U.S. employees to be vaccinated in accordance with Biden’s vaccine mandate for federal contractors. Other companies like Amtrak, Boeing, and major U.S. airlines have announced similar accordance policies for their employees. The White House is planning to add vaccination mandates as clauses to their future government contracts.
