Broadcast union Bectu has claimed that the threat of legal action by the BBC has forced it to call off plans for industrial action over the ongoing sale of BBC Technology (BBCT).
Bectu has been protesting on behalf of BBCT and News IT support staff about the transfer of BBCT to Siemens Business Services in a £2bn deal.
Plans to strike on 13 and 14 August, timed to disrupt the BBC's coverage of the opening weekend of the Olympic Games, have been withdrawn.
Bectu claimed that the cancellation of the strike came "after the BBC threatened to take Bectu to court".
Bectu said that, according to the BBC's lawyers, any plans to strike while the latest offer on terms and conditions for staff is being considered would need to be ratified by a completely new vote, rather than a revisit of the previous decision.
Bectu, which represents over a quarter of BBCT's 1,400 staff as well as 80 News IT staff, has planned such a follow-up vote on 12 August rather than hold a new ballot.
But in a statement the BBC said "The BBC has not, at any time, threatened Bectu with legal action.
"Obviously the BBC has been consulting with its lawyers all through this process as it is a major commercial deal, and the BBC would want to protect its interests during this period. The deal is still on track to complete this autumn and we are in the final stages of negotiating the contract."
Gerry Morrissey, Bectu assistant secretary, said in a statement: "There are still a significant number of issues unresolved between Bectu and the corporation concerning BBCT which, if not resolved, will lead to a further ballot for industrial action."
The union is now in the process of consulting staff on other issues and concerns arising from the transfer, and has not ruled out moves for further industrial action, even though it has withdrawn its objections to the latest offer from Siemens in favour of a 'neutral' position.
