Scottish soap River City has become the centre of a BBC investigation, after numerous complaints of bullying on the set.
One crew member was fired last week, according to The Herald, with tensions between the show's bosses and production staff now said to be fraught.
The hiring of a new executive producer, EastEnders' Kathleen Hutchison, back in April allegedly led to an "extremely aggressive management style".
Scottish organiser for union BECTU Paul McManus - whose group represents over half the River City staff - had a meeting with BBC Scotland's head of talent Donald Iain Brown last month, in which he raised concerns.
McManus also wrote a letter following the crew member's sacking: "The new management at River City appear to us to have adopted an extremely aggressive management style which we believed was tantamount to bullying in some cases.
"In recent years, River City has filmed twice as much script as EastEnders in the same amount of time with a much smaller budget. We've been saying to the BBC that they are putting people under too much pressure."

A BBC Scotland spokesperson said: "BECTU, who we have a very good working relationship with, had raised a number of issues with us on behalf of members who work on River City.
"We take any staff concerns over working conditions very seriously and we're therefore working with BECTU to investigate the issues raised and establish the facts as a matter of urgency."
