The company originally operated the NILGOSC final salary pension scheme for all employees, but around 1995 it closed membership to the scheme, and all new recruits after that were given a different pension scheme where the employee and employer both contribute 6% of salary. Over the past few years, the employers contribution to the NILGOSC scheme has risen significantly ( I think it's currently around 28%), and the reason for withdrawal from the scheme is to reduce the costs associated with it. Members will lose a significant amount of benefit on retirement, and as yet the company has only made a very small offer of compensation, which everyone has rejected. It would appear that the company feel that getting any agreement that suits them is unlikely, and this is now their way of forcing the change through. At this stage, I would like to know if it is legal to dismiss employees, and then offer them another contract that leaves them significantly worse off in retirement.
