2015 and on.... inflation
Be very careful what you agree to now... most pundits seem to believe that inflation will rear its ugly head from next year, so a 3 year decreasing deal must seem like a dream come true to the management negotiators.
maybe in 2016 when you're paying 14%+ for your mortgage and $50 for a can of beans the mists will clear in your addled (maybe too tired) brains and you'll grow a spine for the next round of 'negotiations'
... by the way how's the contract that penalises the Company for any change to the published roster coming along?
