Workers at Mercedes Benz Group AG (OTC:MBGYY) (OTC:MBGAF) factory in Vance, Alabama, petitioned U.S. regulators for a union election, the United Auto Workers (UAW) announced on Friday.

The SUV plant is the second to seek an election petition with the National Labor Relations Board (NLRB) in recent weeks. Mercedes workers aimed to file the petition this week.

The UAW claimed a "supermajority" of more than 5,000 eligible workers at the plant signed cards to join. A vote is anticipated by early May, reported Reuters.

The UAW also accused Mercedes of violating Germany's global supply chain law, which the company denied, stating its recognition of employees' rights to organize.

The move for an election followed extensive organizing efforts across non-union automakers including Hyundai Motor Company GDR (OTC:HYMTF), Toyota Motor Corp (NYSE:TM), Tesla Inc. (NASDAQ:TSLA), and Rivian Automotive Inc (NASDAQ:RIVN).

UAW President Shawn Fain aims to bring a new automaker into the union fold after successful contracts with General Motors Co (NYSE:GM), Ford Motor Co (NYSE:F) and Stellantis NV (NYSE:STLA).

President Joe Biden is an ally and UAW's efforts are backed, especially in battleground states like Michigan.

In Chattanooga, Tennessee, Volkswagen AG (OTC:VWAGY) workers sought a UAW vote, anticipated by April 19, following prior unsuccessful attempts.

Price Action: MBGYY shares are trading up 0.40% at $20.19 at publication Friday.
