Halliburton has reduced its headcount in North Dakota as the low oil price continues to hit companies.
The move comes after it was revealed the US Department of Labour had forced the oilfield service company to pay back more than $18million in unpaid overtime.
A spokesman for Halliburton said it would be continuing to “monitor the business environment” of its workforce “to align with current business demands as needed”.
Earlier this year the company said it planned to reduce its headcount by more than 6,000 positions worldwide in response to falling oil prices.
In November last year the company agreed to buy Baker Hughes in a $34.6billion deal.
