Thousands of BBC workers are to be balloted for strike action over job cuts at the corporation.
Ballot papers for 10,000 members of the NUJ, Bectu and Unite unions go out this week.
The BBC is planning to slash 2,500 jobs and has not ruled out compulsory redundancies.
Unions say the BBC is preparing to select workers for compulsory redundancy and accuse the corporation of “cherry-picking” workers.
The majority of redundancies will come in news, programme-making and regional centres.
Further compulsory redundancies are threatened in BBC Scotland and other parts of the corporation, including the World Service, Nations & Regions, Future Media & Technology, and Audio & Music.
Gerry Morrissey, Bectu’s general secretary said, “The BBC has left us with no option than to ballot our members for strike action.
“I am confident that we will get an overwhelming ‘Yes’ vote and that very successful strike action will take place at the beginning of January.”
NUJ General Secretary, Jeremy Dear, said, “We’ve been very clear with the BBC that any attempt to force through compulsory redundancies will result in a ballot for industrial action.
“Our members are already deeply concerned about the strain they will be put under as a result of the BBC’s cutbacks.
“Now management is piling on the pressure by leaving thousands of people uncertain about whether they will have a job in the new year, even though it appears that many of these cuts could be dealt with through voluntary redundancies.”
On top of the 2,500 job cuts, the BBC plans to withhold unpredictable hours allowances from new staff from 1 January 2008 and implement changes to the pension scheme from April 2010.
Ballot papers will go out on Friday and the ballot closes on 9 January 2008.
