I would say that the rail unions have upped the ante so much now that it is past just inconvenient. The baggage handlers' strike is inconvenient, the rail unions have lost people their jobs, closed down businesses and put pressure on family life.
I'm not against strikes per se, but there needs to be a limit. At the moment unions can strike as much as they like, providing they hold a ballot etc.
What would be your reaction if all hospital staff went on strike for 6 consecutive days, or teachers? Then another 3 days, then another 3...
The question's been asked many times before, but if it's about drivers operating the doors, why are other regions (who have had this system operating for a while) not on strike?
Which is why they can afford to strike for 6 days in January, and no doubt many more days after that. Guards are quite well paid, for what they do, too.
