Unions may decide to ballot staff today and any strikes could take place within weeks, affecting flagship shows including the news, live entertainment ratings winners such as Strictly Come Dancing, live sports coverage and, if the action is sustained, even long-runningserials such as EastEnders. The job cuts are likely to be divided in the main between the news and factual divisions, with factual reportedly losing up to 735 posts - probably translating into as many as 660 redundancies.
