Federal Judge Upholds Southwest Airlines Vaccine Mandate

The Airlines Pilots union is opposing a vaccine mandate requiring all Southwest Airlines employees to be fully vaccinated by December 8th, as part of President Biden's mandate for government contractors. The union argues that the mandate should be negotiated as it alters work and pay rules. Despite a judge's ruling against them, the union is disappointed and considering further actions.
