More than 100 staff face losing their jobs at the Theatre Royal in Plymouth.
It was announced on Monday 22 June that the charity has begun redundancy consultations, affecting almost a third of all staff.
The theatre's Chief Executive says the revenue lost by the Covid-19 pandemic is the reason jobs are at risk - a move he said is "painful but unavoidable".
Since lockdown began three months ago, the venue's income has been slashed by more than 90%.
A number of stars have shared their disappointment at the news:
Adrian Vinken says the uncertain future of the furlough scheme and when they can reopen will put their "depleted funds" under more pressure.
The loss of 91% of its revenue since March is due to productions being axed and refunds being issued to customers.
Recently, TRP’s active staff members volunteered to reduce their salaries by 20% in a bid to support the charity.
It’s heartbreaking that what was a thriving organisation worth £40+million annually to the local economy just weeks ago has been forced to implement redundancies to safeguard the future. It’s a terribly sad outcome for such loyal and capable staff – but a regrettable and inevitable result of the ongoing crisis.
Though an opening date for TRP has yet to be confirmed, tickets for productions in 2020 remain on sale, including the Christmas pantomime, Aladdin.
