Bottom line is that this is probably the most important benefit that people work for. Closing the scheme i believe was inevitable but one step too far with the cap which unless payrises stay below rpi+.5 then we stand to lose out. This has left people with the good will and effort that they have put in ie extra sectors, meetings/working groups as a kick in the teeth and inevitably the withdrawal of this by some individuals inevitable if a yes vote. Also the union are probably aware of the possibility of potential subscription cancellations as a result of how strongly some feel. Yes working to rule is a form industrial action, but people who decide their rostered time off is now more important to them, than a working group meeting it is very difficult to pin on anyone.
As for the vote myself either way it goes i will respect the majority, even if I feel we have lost the hold on the dearest thing to most of us.
