Charlotte, N.C. — Service workers at Charlotte Douglas International Airport have gone on strike during a busy week of Thanksgiving travel to protest what they say are unlivable wages.

Employees of ABM and Prospect Airport Services cast ballots Friday to authorize the work stoppage in North Carolina, which a spokesperson said began Monday morning.

Officials with Service Employees International Union announced the impending strike in a statement early Monday, saying the workers would demand “an end to poverty wages and respect on the job during the holiday travel season.”

ABM and Prospect Airport Services contract with American Airlines to provide services including cleaning airplane interiors, removing trash and escorting passengers in wheelchairs.

Workers say they previously raised the alarm about their growing inability to afford basic necessities, including food and housing. They described living paycheck to paycheck, unable to cover expenses like car repairs while performing jobs that keep countless planes running on schedule.

“We’re on strike today because this is our last resort. We can’t keep living like this,” ABM cabin cleaner Priscilla Hoyle said in a statement. “We’re taking action because our families can’t survive.”

Several hundred workers were expected to walk off the job and continue the work stoppage throughout Monday.

Most of them earn between $12.50 and $19 an hour, which is well below the living wage for a single person with no children in the Charlotte area, union officials said.

Charlotte Douglas International Airport officials have said this holiday travel season is expected to be the busiest on record, with an estimated 1.02 million passengers departing the airport between last Thursday and the Monday after Thanksgiving.

In addition to walking off the job, striking workers plan to hold a late-morning rally and a “Strikesgiving” lunch “in place of the Thanksgiving meal that many of the workers won’t be able to afford later this week,” union officials said.

“Airport service workers make holiday travel possible by keeping airports safe, clean, and running,” the union said. “Despite their critical role in the profits that major corporations enjoy, many airport service workers must work two to three jobs to make ends meet.”

ABM said it would take steps to minimize disruptions from any demonstrations.

“At ABM, we appreciate the hard work our team members put in every day to support our clients and help keep spaces clean and people healthy,” the company said in a statement last week.

Prospect Airport Services said last week that the company recognizes the seriousness of the potential for a strike during the busy holiday travel season.
