Musicians from London Chamber Orchestra (LCO) walked out of a rehearsal on 7 February ahead of a performance in protest over unpaid wages.
Around half the players, who are all freelance, took action after voicing objections to five months of overdue payments, according to a report in The Observer. A subsequent performance by LCO at Cadogan Hall went ahead after other musicians were brought in to cover.
Jocelyn Lightfoot, the ensemble's Managing Director, said the issue arose after Barclays Bank froze LCO's account “with no prior warning". The action was part of Barclays' anti-crime measures.
Lightfoot said: “We kept the musicians informed during this period that their payment would go out as soon as the account was reopened, but as the timeline of the reopening was further delayed many times, it was difficult to provide musicians with a clear timeframe.
"We understand the monumental strain on this body of freelancers whose opportunities to work have been reduced and jeopardised due to sweeping cuts to orchestral funding.”
She confirmed that the payments have since been made.
A Barclays Bank spokesperson said: “We take the protection of our customers’ funds and data extremely seriously.
“As part of our ongoing responsibility to help prevent financial crime and to meet our regulatory responsibilities, we are required to ensure we hold up-to-date information regarding our customers’ accounts. Customers are also required to inform the bank in a timely manner of any change to their legal status relating to their business, charity or trust.”
Barclay’s anti-crime measures are understood to have affected other organisations, including the classical music venue, St John’s Smith Square, Surrey-based Clockwork Charitable Trust and the Ogmore Valley Male Voice Choir.
