Musk has made changes to the budget of the micro-blogging site.

According to an email sent by the company's HR department and seen by Insider, the company is entering a new phase of spending austerity under Musk's ownership. A number of perks will no longer be paid for by the company. The maximum amount of work-related trips that can be taken has been limited.

"We are facing a challenging economic climate where more attention to cost management is needed," the email said. If we can work together to be wise stewards of the company's resources, the future is bright.

The perks that are being "discontinued" include all costs associated with "wellness," "productivity," and "new hire productivity," along with home internet or wi-fi costs, training and development or "learning," according to the memo. The temporary allowance to cover daycare costs is no longer available.

When the company's financial situation improves, allowances may be added back, according to the email.

A former employee said that the training and development allowance had been a part of the social networking site for a long time. Tech companies usually have expenses for group or team activities.

Expenses for other work related costs have been lowered as well. The daily allowance for food while on a work trip is now $75, and the monthly allowance for a mobile phone is $50. The overall limit on expenses for work related travel has been "revised" according to an email.

A cost estimate will need to be approved by a manager before any arrangements can be made. While a manager or senior manager can only spend up to $500 for a work related trip, a vice president can spend up to $10,000 and a senior VP can spend up to $20,000.
