This. London's tube system is essentially stopped a day or so a year due to strikes, which is pretty dramatic for a city of 10 million people who rely on it.
London's transport strikes have been shown to ultimately benefit the wider economy, as people have broken out of their local maximums and found more efficient ways to travel around.
Perhaps the drivers should be paid a sum of money which closer reflects how much marginal value they add to the city, and this would convince them not to strike.
