I'm probably wrong but I thought the only difference was that the first one offered inflation-linked pay increases in 2011 and 2012 capped at 4%, and in the second one the cap was 3%.
In other words, no difference unless inflation in either of those two years exceeds 3% (is that likely?)
The big difference now is that the militants who have lost ST have less incentive to stay, if they go their replacements won't cost the company so much.
