This particular office chum won't be taking any industrial action likely to preserve the pensions of operational staff at the expense of my job. The amount I might lose in pension by the RPI cap pales into insignificance compared to the amount lost if I'm not a member of the scheme until retirement.
And with management having won this battle due to a divided workforce, when they come for your job in a future cost cutting exercise, you won't mind if everyone else just looks the other way I guess ??
