Maine casino inspectors have signed a letter of no confidence in the head of the Maine Gambling Control Unit.

The letter comes amid complaints that Executive Director Milton Champion is creating a toxic work environment.

Inspectors also claim Champion changed their work schedules out of retaliation after they voiced concerns.

Champion has been under fire in the past.

Last year, he was suspended for one-week without pay for tweeting a sexist slur.

All nine inspectors signed the letter of no confidence although it’s unclear what next steps could occur.
