Border staff threaten strike chaos before Olympics The PCS said 57 per cent of its members had backed strike action after 16,000 Home Office staff were balloted and three quarters had voted for other forms of industrial action. Mark Serwotka, the PCS general secretary, and other leaders will meet today to decide the next move but a spokesman warned that they have to give only seven days notice for a strike. However, only 20 per cent of those balloted responded, meaning that around one in ten effectively backed strike action. Dominic Raab, the Tory MP, said: "For Mark Serwotka to threaten to target the Olympics when just 11 per cent of his own members back a strike, is self-indulgent, reckless and unpatriotic. There is no credible basis for this vindictive strike action - a militant minority led by a union head-banger should not be allowed to wreck the Games. Mr Green added: "I call on the union to call off this irresponsible proposed strike. Only about one in 10 PCS members voted for strike action. The union leadership has no authority to call disruptive strikes on that basis and should think again. The PCS claims to represent around 5,000 of the 7,300 Border Force staff although those figures have been disputed. The Immigration Service Union claims to represent around 4,000 Border Force staff. The PCS is in dispute with the Home Office on plans to cut 8,500 jobs, the threat of compulsory redundancies in the passport office in Newport, South Wales, a one per cent pay rise cap following a two-year wage freeze, privatisation of services, and alleged victimisation of union representatives. Mr Serwotka said: "Ministers have known about these issues for a very long time but have chosen not to act. We believe they have acted recklessly and irresponsibly in cutting so many jobs and, in the case of the UK Border Agency, they have simply tried to paper over the cracks by deploying severely under-trained staff at our borders.
