Millions of Brits face travel chaos today due to a massive train strike that is the biggest in a generation - but if you can't get to work, does your employer still have to pay you?
Around 50,000 members of the Rail, Maritime and Transport (RMT) union at Network Rail and 13 train operators are walking out after last-ditch talks failed to resolve a dispute over pay, jobs and conditions.
Strike action will affect trains today, Thursday and Saturday.
