You're right that there is nothing that can be done about the company taking a pension holiday, except the Union could make their opposition to it clear, if that is what they think is the case. Obviously the Union has been negotiating some sweetener for the members but have they told anyone what they are up to? Not as far as I am aware. I for one would rather have been consulted about what is going on than read rumours in Private Eye. If the Trustees are against this (and they have managed the fund perfectly well for some time now) why are the Union so keen to go against their advice?
