June 10 (Reuters) - United Auto Workers President Shawn

Fain is under investigation by an independent federal monitor

over allegations of retaliation against other union leaders,

according to a court filing on Monday.

Monitor Neil Barofsky opened an investigation in February to

review allegations, including that the UAW secretary treasurer

said she had faced retaliation for her refusal or reluctance to

authorize certain expenditures for Fain's office, according to

the filing. Barofsky also opened a probe into the secretary

treasurer's actions. The UAW declined to comment.

Barofsky was appointed the federal monitor in 2021 as the

UAW grappled with a corruption scandal that resulted in the

federal convictions of several former leaders. Two former UAW

presidents were sentenced to prison time as part of the probe.

The monitor expanded his investigation to also include

allegations made by Fain against the leader of the union's

Stellantis ( STLA ) department. Fain took over the Stellantis ( STLA )

department leader's duties at the end of May.

Fain alleged that the Stellantis ( STLA ) department head's

responsibilities were reassigned because of their "dereliction

of duty" in connection with collective bargaining issues.

The monitor later received complaints that Fain's decision

was an act of retaliation because the Stellantis ( STLA ) head refused to

engage in acts of financial misconduct to benefit others,

according to the court filing.
