On Tuesday afternoon, Tesla pro-union leaders marched towards the factory of Tesla in Fremont, California, seeking to unionize the employees of Tesla. The union group condemned the recent firing of workers at Tesla and accused the automaker company of of targeting employees who earlier made complaints about the working scenario inside the factory.

A spokesperson of Tesla rejected the claim of the union supporters but made a comment that the company “respects their right” in the protest. Earlier this month, after a round of performance reviews, a number of Tesla workers were fired, whilst the company struggles in ramping up the production of model 3.

The group that made this protest against the latest firing at the company include some community leaders and fired workers, conveyed a letter to the company denouncing the firings.

The letter of the pro-union reads in part; “We see Tesla as an important company for our regional economy, employing thousands of workers in the extended Bay Area who are proud to be building a zero-emission electric car. Given its importance, we expect Tesla to be a responsible employer that leads with fair treatment of its workers.”

On Tuesday night, a spokesperson of Tesla responded to the demonstrations in an e-mail to the Business Insider, saying; “At Tesla, we strive to be a fair and just company, the only kind worth being. No one at Tesla has ever or will ever have any action taken against them based on their feelings on unionization.”

“Some employees recently left Tesla, but what has not been reported is that a much larger number – 17% of our employees – were promoted, and almost half of those promotions were within our factory in Fremont.”

The timing of these firings raised an alarm for the Tesla Company because it missed its production goals of September for it’s newly released, first ever mass-market electronic car, the Model 3. The company managed to produce only 260 Model 3s in September, which is far short from the stated goal it made cranking out 1,500 that particular month. The company struggled with “production bottlenecked”.
