DENVER — Shuttle bus drivers at Denver International Airport could soon go on strike. The shuttle drivers say it’s all about the money and they want more of it.

Meanwhile, timing of a potential strike hasn’t been ironed out. The airport says it will be working to mitigate any issues. But within the next week or so, drivers say a strike could be called as negotiations falter between drivers and their employer— ABM.

DIA says it is working closely with ABM on contingency plans to ensure airport operations are not impacted.

“They’re going to take care of it,” one traveler said. “They’re not going to let it get there.”

The details of what the airport would do are unknown.

“It would be a long walk [if there are no drivers], yeah, it wouldn’t be too good,” another traveler said.

Drivers would not talk to FOX31 on camera Tuesday amid pressure not to talk to media. Their employer put out directive on the shuttle radio system.

“We do need you guys to let [the media] know to contact the office,” the voice said over the shuttle bus’ radio.

“ABM and the United Mine Workers have been working hard to achieve an agreement which recognizes the valuable contributions of our employees and respects our client’s need to control public spending,” ABM said in a statement.

“As of this evening, our employees are considering a revised settlement package which — if authorized by employees — would provide for significant wage increases, preserve quality health insurance, and recognize our long-term employees.

“We expect the approval process to continue through this week and we do not anticipate work disruption during the approval process.”
