There used to be only 2 certainties in life - death and taxes. Now there is a third - WW will get his cost reductions and he ain't gonna get that by just losing a single crew member on LH. He will get the new fleet, he will get more work out of LHR SH through LGW crewing levels and if a ballot is called then the cost of that to BA will be added to the IFCE cost-saving target. Expect more imposition, lots more. WW's reputation and the financial viability of the company are on the line, he cannot afford to lose.
