ElonMusk said:“Most of our experienced factory workers come from unionized environments, and we asked them what benefit did they see in unions,” he added. “They said, ‘Well, if their boss was an *******, they had recourse.’
“I said, ‘Let’s make a rule: There will be no *******s.’ I fired someone for being an *******. And I only had to do that once, actually.”
