Workers at Tesla Inc.'s (TSLA  ) Berlin facility are voicing growing unease about safety issues and intense working conditions, as revealed by the German union, IG Metall.

On a recent Monday, the Gruenheide plant near Berlin witnessed over 1,000 employees donning stickers demanding "safe and fair work," according to a report from Bloomberg. The plant is home to approximately 12,000 staff members.

The core grievances the employees highlight pertain to challenging working environments, elevated work demands resulting from understaffing, and aggressive production objectives.

IG Metall, a union wielding significant leverage in competitors like Volkswagen AG (VWAGY  ), has observed a surge in Tesla employees enlisting with them.

The auto sector is witnessing a mounting demand from its workforce for enhanced salaries and job stability, particularly as the industry shifts towards electric vehicles (EVs).

With EVs necessitating fewer components and workers for production, there's rising apprehension about potential job losses and wage cuts. Such sentiments have triggered the United Auto Workers union in the U.S. to initiate major strikes targeting key players such as General Motors Co (GM  ), Ford Motor Co (F  ), and Stellantis NV (STLA  ), leading to production stoppages in several facilities.

Elon Musk, Tesla's CEO, has historically demonstrated limited patience for union activities. Earlier in the year, when a faction of Tesla's Buffalo, New York workforce began a unionizing initiative, their employment was promptly terminated.

Over the recent years, Tesla has faced setbacks in multiple National Labor Relations Board verdicts, including a notable decision in August 2022 prohibiting workers from sporting union-supportive attire.

In Germany, Tesla has chosen not to adhere to normative wage agreements in the nation, leading to a potential confrontation with the extensive 2.2 million-strong IG Metall.

Price Action: TSLA shares are trading lower by 2.53% at $253.88 on the last check Monday.
