Crews in GLA are OK for the moment.
Problem arises at the end of the current wet lease. SG is highly unlikely to want to diversify his fleet by taking on the ATPs himself, more likely to hang onto the routes and acquire more Saabs. Probably jobs there (along with huge pay cut) for those whose faces fit.
They will probably prefer to stay with CX - assuming it is still there; however that would de facto involve a move Southwards to whatever English bases are left by then - probably only MAN and BHX. Best guess would be a further subsidy wet lease involving less cash from SG - it all really depends on what the latest bean counting strategy is from Waterworld at that point.
