Judging from some comments elsewhere, I think many CC may have now learned the hard way that a vote in favour of industrial action should be just that - a vote to say I am prepared to withdraw my labour with all the consequences that entails and nothing else.
It was repeated many times during the ballot process that CC voted in favour of industrial action to "send WW a message" or to "bring WW back to the negotiating table". That has clearly failed. The union has also taken the mandate for industrial action and wreaked havoc with it, calling the 12 days of Christmas strike, calling the March strikes even though WW allowed an extension to the strike deadline to let CC be balloted on the offer on the table and now the 20 day strike action which seems to be collapsing 6 days into the 15 days of actual strike action.
I really hope for everyone's sake that BA is able to recover from this both financially and in terms of customer service.
