Gary Jones, the president of the United Automobile Workers union, which is under investigation over allegations of financial wrongdoing, is taking a leave of absence, the union said in a statement on Saturday.

The union said Mr. Jones sought the leave of absence after a vote by its executive board. The statement did not elaborate on the board’s vote and Mr. Jones could not be reached on Saturday for comment. Mr. Jones has not been charged with wrongdoing in the investigation.

In August, agents from the Federal Bureau of Investigation raided his home in Canton, Mich., and executed search warrants at a U.A.W. resort in Michigan and other locations, the agency said at the time.

In particular, investigators have been looking into the resort, Black Lake, a rustic lakeside conference center with golf courses, tennis courts and log-cabin style architecture in Onaway, Mich., about 250 miles north of Detroit.
