Welcome to the 21st century - people can't be fired for taking part in lawful industrial action
Perhaps it should be me welcoming you to the 21st century: you can indeed be sacked for taking part in lawful industrial action. The moment you go on strike you are in breach of contract and thus can be sacked. I am not going to explain to you what happens as I'm sure you have read it all in the previous pages on this topic re the protection involved.
