After procedural delays, workers at a Tesla battery factory in Nevada filed their latest ULP complaint last Friday. The complaint reiterates charges that the UAW filed on November 15, which claims that Tesla fired workers who were openly engaging in union organizing activities. The partially reduced complaint alleges that the company had surveilled, intimidated, and interrogated workers who’ve engaged in perfectly legal organizing activities. The filing is just the latest of multiple ULP complaints filed by Tesla employees across the country. In August, workers at an assembly plant in Fremont, California, filed a complaint with the NLRB claiming that Tesla had interrogated employees over union activates.
