The Pacific Northwest National Laboratory plans to lay off 45 employees this week. The cutbacks are in order to adjust to the latest federal budget approved in December, the Associated Press reports.

The Department of Energy national lab based in Richland employs 4,758 people and gets 93 percent of its budget from federal agencies.

The 45 layoffs that could come this week are in addition to almost 70 layoffs in the past 12 months, which included 23 voluntary layoffs. Only a couple of the 45 layoffs this week will be voluntary.
