The unions argue that the Omaha, Nebraska-based railroad should have negotiated with them before announcing it would require all employees to get the shots. The railroad contends in its own lawsuit that it believes it has the authority to require the vaccine under its existing contracts because it can set standards for when employees are fit for duty.
Union Pacific announced this month that it would require all employees to be vaccinated by December 8 to comply with an executive order President Joe Biden issued requiring all federal contractors to have their employees vaccinated. The railroad is also offering its union employees a $300 bonus if they get the shots. Nonunion employees at the railroad are being offered a half-day of vacation if they get vaccinated.
