Hospitality workers employed by the charity, which runs the Theatre Royal and the Playhouse Theatre in the city centre, had their contracts terminated last week. Norwich Theatre said the dismissals come as part of an investigation into "extremely serious matters". Norwich Theatre "strongly refutes" this claim. A spokeswoman for the theatre said: "Norwich Theatre strongly refutes any suggestion that the organisation has acted in any way unreasonably, unfairly or unlawfully towards workers. The Norwich Theatre spokeswoman was unable to comment on exactly how many members of staff were dismissed.
