Under UK law, provided that a union has followed the correct procedures, striking is not illegal and therefore you cannot be sacked / fired / dismissed / persecuted etc. The Company would therefore be unable to "replace" a striking worker.
On the "easy" deal.... I think it was a reasonable result under the circumstances. It puts a two year line capt on about £85k - that's not too bad and it is a first step - there will be negotiation in future years.......
The next issue is lifestyle and it does appear there is a glimmer of recognition on the part of the company that they need to address this issue if they don't want a repeat next year, of this years "problems" - which I think are completely unforgiveable and those responsible should pay.
Good luck to all parties in your battles - but keep it real.
