ExxonMobil said Thursday that it intends to reduce its U.S. staff by around 1,900 employees, with global workforce reductions potentially rising to as much as 15% as the energy giant continues to see its operations pressured by the coronavirus pandemic.

The U.S. layoffs will occur through a mix of voluntary and involuntary programs, CNBC reported. Exxon said the reduction is part of ongoing reorganization efforts aimed at improving efficiency and reducing costs.

These actions will improve the company’s long-term cost competitiveness and ensure the company manages through the current unprecedented market conditions,” CNBC quoted the company to have said in a statement.

“The impact of COVID-19 on the demand for ExxonMobil’s products has increased the urgency of the ongoing efficiency work.”

Earlier in October Exxon said it was cutting its European operations by 1,600 positions through the end of 2021.

An Exxon spokesperson told CNBC that the company is conducing country-by-country reviews, which could result in a 15% reduction in its global workforce. The company anticipates 14,000 contractors and employees to be affected by the already announced programs. As of the end of 2019 Exxon had 88,300 employees.

The announcement comes as the oil and gas industry continues to feel the pain of the coronavirus pandemic. West Texas Intermediate, the U.S. oil benchmark, has recovered since plunging into negative territory for the time time on record in April, but the contract still trades at a deep discount to prior prices.
