Broadcasting union Bectu has warned that up to 350 jobs could be at stake following the BBC's confirmation that it is to sell its commercial BBC Technology arm.
The BBC said it had decided to sell the company - a move exclusively revealed by Broadcastlast week - in order to save between£20m and£30m a year as well as to safeguard jobs at the division. It claimed that if it stayed within the BBC big savings would have to be made.
However, Bectu has said any company which buys the subsidiary - which employs 1,400 people and specialises in IT provision - would still make job cuts.
"We are convinced that any new owner, in order to meet the BBC's price targets, will have to make its own cuts," a Bectu spokesman said. "It is patently obvious that there are going to be redundancies after the sale."
Alongside the sale, Roger Flynn, chief executive of the BBC Ventures group - which encompasses BBC Technology as well as BBC Broadcast, BBC Resources and BBC Vecta - is to step down in the spring following his review of technology provision at the BBC.
One of his last tasks will be to review the BBC Ventures set-up itself - which could lead ultimately to its disbandment - although the BBC has said it is not looking to sell any of the other commercial companies.
The sale of BBC Technology is expected to go through by autumn next year although it will have to be greenlit by media secretary Tessa Jowell.
