LOS ANGELES – An $8.8 billion Australian transportation corporation has escalated its attack on its Latino-American workers by firing a mother of three for stopping to use a McDonald’s restroom during her delivery route. The cruel termination of Xiomara Perez, a 46-year-old port truck driver who has already been outspoken about the filthy, unsanitary outhouses that lack running water at her worksite, occurred amidst a rise of pro-union solidarity actions by Perez and her co-workers.
