According to a recent complaint, employees at a Tesla factory in Buffalo, New York were fired the day after plans were announced to unionize at the location. The organizing efforts are being led by Tesla Workers United, and the group shared that Tesla updated company policy to prohibit recording of workplace meetings without all parties' consent on Wednesday. As a result of this new policy, several workers were fired and have expressed feeling retaliated by the company for organizing. The union has filed a claim with the NLRB for unfair labor practices and is determined to continue its union campaign at the factory.
