U.S. President Joe Biden's top labor adviser, Celeste Drake, has stepped down, according to a source with direct knowledge of the matter, as the administration attempts to maintain labor peace and avoid threatened strikes during an election year.

Drake is leaving the White House to serve as the Deputy Director-General of the International Labor Organization (ILO), based in Geneva, Switzerland, and starts in her new role on Aug. 14, according to the source, who did not wish to be named.

The ILO did not immediately respond to an emailed request for comment.
