Southwest pilots' union sued the carrier this week, alleging the airline violated federal labor laws by altering work rules during the pandemic travel slump without negotiating the changes.

Those included changes to work conditions and pilot pay rules and rates, such as an "emergency" time-off program, according to the lawsuit, which the Southwest Airlines Pilots Association filed in federal court in Dallas on Monday.
