Southwest Airlines told workers they could lose their jobs in January after cost-cutting talks stalled.
The possible furlough would be the first temporary layoff in the carrier’s 50-year history.
Dallas-based Southwest issued the notices to 42 material specialists.
The announcement comes after failed talks over a company proposal to cut wages by 10% in 2021.
Southwest has also warned flight attendants and others that furlough notices could be coming soon.
