Tesla's General Assembly plant maintained the following dress code: "It is mandatory that all Production
Associates and Leads wear the assigned team
wear." For production associates, "team wear" consists of a black
cotton shirt with the Tesla's logo and black cotton
pants with no buttons, rivets, or exposed zippers, all which Tesla provides.
In the Spring of 2017, however, certain production associates started wearing black t-shirts with the phrase, "Driving a Fair Future at Tesla," along with the logo for the United Auto Workers.
Tesla banned the UAW shirts under its "Team Wear" policy, claiming that the ban limited the risk of alternative clothing damaging vehicles on the production line and made it easier to keep track of employees on the shop floor.
In a split 3-2 decision, the NLRB held that Tesla unlawfully prohibited its employees from wearing shirts with the UAW's logo.
