[article] OAKLAND, Calif. — Food and retail workers at the Oakland International Airport said Thursday that they plan to strike at some point during the holiday season to protest what they say are unfair labor practices, including low wages. Sarah Norr, a spokesman for Unite Here Local 2850, which represents about 200 employees at the airport, said the date and length of a strike haven't yet been set but workers plan to walk out at some point between Thanksgiving week and the end of the year. Food and retail workers previously staged a one-day strike at the airport on Aug. 30. The workers are employed by HMSHost, a Maryland-based company that won a 12-year contract for services at the airport, which is run by the Port of Oakland, in 2006. HMSHost runs food concessions at more than 100 airports around the world, according to the company's website. The employees have been working without a contract since July 2012.
