The Citadel Theatre is apologizing for what it is calling a history of workplace harassment.

In a letter released on Tuesday, artistic director Daryl Cloran said he’s heard from many artists with negative experiences, and promised that disrespectful behaviour will not be tolerated anymore.

“I have spoken with many artists, and it has become clear to me that through its history, there have been times that the Citadel has been a negative workplace for artists and staff. That is unacceptable,” wrote Cloran.

He says that when he first arrived in September 2016, he learned of several allegations of workplace harassment, and the board and management started addressing them immediately by beginning a “safe disclosure process.”

Since then, the Citadel has reviewed its code of conduct and joined an anti-harassment program called “Not In Our Space.”

“We are truly sorry for any harassment that has been part of the Citadel’s past, and we give our word that anyone who engages in bullying or harassment will not be permitted to work at the Citadel.” Tweet This

The theatre is also bringing in human rights advisor Wade King for anyone else who wants to share their story in confidence. It is also planning a May 14 community event for artists where they will acknowledge the past and make an inclusive plan for the future.
