Elon Musk has never been the most professional business owner in the world, and he certainly wouldn’t earn the title in recent days.

The new owner of Twitter (the “Chief Twit”) has been clashing with his own employees publicly on Twitter, even firing them through the social media platform.

Musk appears to be feeling a little vulnerable and fragile as employees levy criticism against his takeover of Twitter, and he’s handling it like a baby with a soggy diaper.

On Monday, for instance, Musk got into an argument with software engineer Eric Frohnhoefer that ended when Musk tweeted, “he’s fired.”

Frohnhoefer confirmed later that he’d lost access to Twitter’s internal systems.

This came after Frohnhoefer tweeted evidence that Musk was wrong about his claims that Twitter was running, in the words of Musk, “super slow” in several countries.

According to the now-former engineer, Frohnhoefer was sent Musk’s tweet by a friend, and no one from Twitter reached out to him. He says he had been “willing to give it a try” under the new Chief Twit and said he was in the “wait-and-see camp” but confirmed that “everything that has been reported is true.”

Frohnhoefer called Twitter under Musk a “total shit show” and described the state of things as “chaos.”

Musk has fired at least one other employee who offered context to Musk’s claims online. On Tuesday, a handful of other employees said they were fired by email, which told them that their “behavior has violated company policy.” These employees have speculated that their firings have reacted to comments they made in internal Slack channels. According to CNN, employees have been very candid in criticizing Musk in the company’s Slack channels.

Musk, as the emblem of grace and humility he is, tweeted about the firings, “I would like to apologize or firing these geniuses. Their immense talent will no doubt be of great use elsewhere.”

Classy, Musk. Maybe he’ll fight with the lunch lady or his accountant next time. After all, nothing tells investors that you’re a stable and wise investment like arguing with your employees publicly.

Taking a little criticism would go a long way towards reassuring nervous ad companies, but Musk has always seen himself as infallible. He may soon be infallible and alone if he cuts Twitter’s workforce further.
