Strike Action? on the London Underground

So today, or at least continuing throughout today, the RMT union staged another industrial action (aka "strike") on the London Underground. Fortunately, only about 40 out of the 275 stations served by the LU were affected.

In comparison with the union that went on strike on all MTA city buses and trains in New York City, not everyone on the London Underground are unionized. Plus if they did stage a strike, the buses will still run because they are part of another union. Of course they could be sympathetic to the union and would stage a similar industrial action, but they cannot force everyone to leave work. Only a majority of the staff serving London's buses and trains are union members.

At least you got several options to do during an industrial action. If the Tube is out of action, take the bus. If the bus is not available, flag down one of the black cabs. If the cabs are full, just walk. =)
