BBC programmes could be disrupted after broadcasting unions threatened more strikes over the corporation's plans to make compulsory redundancies.
Mark Thompson has said the cuts could save the BBC £355m a year
The BBC is looking to shed 3,780 posts over three years. In December, director general Mark Thompson said about 12% of those redundancies may be compulsory.
Amicus, Bectu and the National Union of Journalists has said the BBC has four weeks to reconsider current proposals.
But the BBC said it "cannot agree to defer redundancies".
Bectu spokesman Luke Crawley said: "We expect the BBC to hold back issuing notice of compulsory redundancy to our members this weekend.
"Bectu does not believe there is any need for these compulsory redundancies and will take industrial action to protect its members interests if that proves necessary."
A BBC statement said the corporation would continue to liaise with the unions and "to do everything possible to minimise compulsory redundancies and to mitigate the effects on staff of the job losses".
"However, in order to deliver the efficiencies and savings needed to invest in the future, the BBC cannot agree to defer the redundancies," it said.
The statement added that, given the three-year timespan, "a large proportion" of job losses could still be achieved through staff turnover and voluntary redundancy.
The one-year freeze on compulsory redundancies is due to expire in July 2006.
Journalists working for regional ITV news bulletins have voted to strike in a dispute over pay.
The NUJ said 58% of its members in England and Wales, excluding London, backed the industrial action.
The NUJ has about 300 members working in ITV regional newsrooms. Turnout in the ballot was 61%.
NUJ spokesman Paul McLaughlin said in light of the speculation over ITV's future, members were "dismayed that although they have taken on new skills and responsibilities, there is not one single penny earmarked for staff".
