UAW vs. Tesla: It's on
Labor relations at Tesla’s Freemont plant in California have are becoming increasingly tense. The UAW has filed an unfair labor practice complaint, alleging rampant employee discrimination, and illegal intimidation tactics against pro-union employees, forcing them to sign nondisclosure agreements prohibiting any discussion of conditions at the plant. The conflict garnered national attention in February of 2017, when an employee published a blog post detaining the harsh working conditions, even reporting on-site injuries. In February, the UAW filed it’s most recent complaint against Tesla, who they say has been terminating employees over the last six months for engaging in union activities.
