CNBC reported on Wednesday thatTesla will keep paying employees who are asked to return home and join the fight against Russia.

For employees who are Ukrainian national and have been asked to return to Ukraine for active duty as a reserve, we will maintain their employment and salary for 3 months, according to executives from the company's Europe, Middle East, and Africa division.

The email was sent by the director of Northern Europe, who was in the midst of Russia's invasion of Ukraine. It is not clear whether the policy applies to employees in other countries.

Ukrainian President Volodymyr Zelenskyy activated the country's military reserves as Russia amassed troops on the Ukrainian border. Ukrainian officials called on men 18 to 60 to take up arms and prevent most of them from leaving the country after the war began. Tens of thousands of Ukrainian nationals living abroad have returned to defend their homeland, according to the State Border Guard Service.

The email was reproduced in full by CNBC and listed some of the actions that the company has taken to support the Ukrainian population. The email said that employees of the company in Germany helped pack and ship the Starlink terminals. The Powerwalls residential energy-storage product was provided by the carmaker, according to the internal email.

Major US firms are supporting Ukraine. Up to 100,000 refugees will be given free housing by the company, according to the CEO. Dozens of giants like McDonald's, Apple, Ikea, and Disney announced they would stop doing business in Russia.
