According to Ars Technica, a federal labor board on Thursday "filed a complaint against Tesla, alleging that the electric vehicle company had discouraged workers from distributing pro-union information, stopped them from talking about employee safety to the United Auto Workers (UAW) union, and in one case, prevented an employee from taking a picture of the Confidentiality Agreement they had to sign." From the report: The Oakland, California-based regional office of the National Labor Relations Board (NLRB) consolidated the complaints of three former Tesla employees, Michael Sanchez, Jonathan Galescu, and Richard Ortiz, as well as complaints made by UAW. The complaint alleges that on numerous occasions between February 2017 and May 2017, security guards and human resources agents working on behalf of Tesla told employees that they had to leave the Fremont, California, factory premises because they were distributing pro-union leaflets. In addition, one employee says that over the course of two meetings, a Human Resources Business Partner and an Environmental Health Safety and Sustainability Specialist "interrogated the employee about the employee's Union and/or protected, concerted activities," as well as the pro-union activities of other employees. In March, the complaint claims, a supervisor told his employees during a pre-shift meeting that they could not distribute any stickers or pamphlets that hadn't been approved by Tesla first, or they would be fired. In another incident, a Human Resources Business Partner allegedly "attempted to prohibit an employee from discussing safety concerns with other employees and/or with the Union."
