In his first email to employees, Musk warned them to prepare for difficult times ahead and to stop working from home.

Musk warned in an email that a weaker economic environment in the US would make it difficult for the company to operate. As a business where ads account for roughly 90 percent of revenue, analysts have been projecting a slower growth in advertising spend in the years to come.

Employees should be able to work remotely, according to Musk.

There was no way to sugarcoat the message. Employees were told that he would only approve remote work on a case-by-case basis and that they were expected to be in the office for at least 40 hours a week. In June, Musk told employees in a Q&A that they would be able to continue working from home.

Musk wrote in the email that the road would require intense work to succeed. The top priority over the next few days is to find and suspend any verified bots.

The management of the site will affect advertising revenue. A number of major companies have paused their ad spend on the site in the wake of Musk's takeover and his plans to scale back moderation.

Musk told advertisers in a public Q&A on Wednesday that they have yet to see any changes to the platform's moderation policies. Musk has accused the same groups of trying to destroy free speech in America and blamed them for pressuring advertisers to drop campaigns.

Many users have been able to masquerade as brands and celebrities because of the change to the verification system. In his emails to staff, Musk said that he wanted the subscription service to account for 50% of the company's revenue.
