UPDATE: Janitors Begin Strike At Denver International Airport Over Wages, Workload

DENVER (CBS4) – Hundreds of janitors at Denver International Airport began a three-day process to vote on a potential strike. The 350 janitors are asking for fair wages and workloads.

The janitor’s union says their employer, Flagship, refused to bargain a contract with them after weeks of negotiations.

The current contract expires on Sept. 30. A strike could potentially start afterward.
