Yesterday on behalf of recently terminated Tesla employees, the UAW international autoworkers’ union filed six unfair labor practice charges against the automaker with the National Labor Relations Board.

Tesla, which has been under fire by UAW organizers and resisting allegations to date, is accused of “intimidating and harassing employees, terminating a group of employees to discourage protected concerted activity, disciplining employees for wearing items with the Union’s logo, terminating and/or disciplining employees in retaliation for participating in protected concerted activities, and more,” according to the UAW.

A couple weeks ago hundreds of employees were let go by the California electric carmaker as it otherwise works behind schedule to ramp up its Model 3 production.

The company is under self-imposed pressure to expand global production from less than 90,000 units last year to 500,000 vehicles by end of 2018 comprised of the 3, Model S and Model X as it also promises a Semi and has other irons in the fire besides.

The automaker has held the line that it is a fair employer albeit without union participation, and meanwhile news reports of unfair practices have come forth with increasing frequency since last year.

In the latest salvo, the UAW’s efforts have intensified its public relations battle to formal charges, and it supported its case quoting disgruntled workers.

“I worked hard for this company for five years, sometimes 72 hours a week – and never had any performance-related complaints,” said Mike Williams in a UAW-produced statement.

The UAW adds he was “let go for ‘performance issues’ and for having a ‘negative influence’ on his teammates.”

“I did, however, wear a union shirt. And I had union stickers on my water bottle. And I believed that a union would make us safer, and would make the company more organized and more efficient,” the ex-Tesla employee said in the UAW-supplied statement. “I hate to think that I was targeted because of it. And it’s not just me. Hundreds of other people were let go with no warning. I want Tesla to know that we are more than just numbers – I have kids, I have a family, and this job meant everything to us.”

Another case example is Richard Ortiz, “an active union advocate for months” who the UAW said “has been quoted in the press multiple times.”

Ortiz filed charges earlier this year noted the UAW, “regarding their unlawful confidentiality agreement.”

The employee was fired, the UAW said, because of a violation of “that very same confidentiality policy.”

“I was fired for trying to better the lives of my co-workers,” said Ortiz in UAW supplied statement. “I always felt this was a worthy fight. I knew it wouldn’t make me popular with management, and I knew there was risk – but people are getting hurt. People are being paid less than they’re worth. And people are being treated unfairly.

“I’ve worked in auto manufacturing my whole life,” Ortiz said. “I do not believe – not for a second – that I was fired for cause.”

Comments from Tesla have yet to come forth.
