PHOENIX — Phoenix Sky Harbor International Airport restaurant workers will strike beginning Monday and lasting through Nov. 29 after union members overwhelmingly voted in favor of a work stoppage last week.

HMSHost, which operates 12 concessions brands at Sky Harbor, including Starbucks, Chelsea's Kitchen, Olive & Ivy, SanTan Brewing and Zinburger, in an email said the union informed them on Saturday the strike would begin this week.

The concessions operator said it is doing whatever it takes to minimize inconvenience over a busy holiday season, with Thanksgiving travel this week expected to return to near pre-pandemic levels.

HMSHost said it has supplemented services with managers, temporary employees and associates from the company’s other locations, in addition to increasing pre-packaged food items and self-pay stations.

It is expected most restaurants, bars and airline lounges will remain open, except for two Starbucks locations in Terminal 3 and a location at the baggage claim of Terminal 4. Zinburger may also temporarily close as well.

Unite Here Local 11 members said they are seeking increased staffing, fair raises, affordable health insurance, a company-paid retirement contribution and tips protection, and that negotiations for a new contract have been going on since 2017.

The concessions operator said it is offering 12% wage increases along with “enhanced benefits” including paying 90% of associate health care costs.

“Unite Here Local 11's decision to strike only serves to hurt the traveling public and the HMSHost associates who continue to work during this difficult time,” an HMSHost spokesperson said in the release.

A one-day walkout was staged at the airport by the union in September over staffing shortages, mainly at Starbucks locations.

A 97% vote of Unite Here Local 11 members on Thursday authorized the strike.
