They aren't stopping anyone else getting to work. I'll admit, I don't know a huge amount what this strike is about (but I'm guessing it's about salary as they mostly are) as it's London, and well, I don't really give a s**t about London.

However, The thing with strikes, is that they are supposed to make things inconvenient for people. Striking in lunch hours isn't going to make any kind of point at all, and no one will sit up and notice.

Unfortunately today, people don't understand the need for unions (and unions are partly to blame for this as well for pushing things way too far at times), but everyone that enjoys holiday, sick pay, and any other work place benefits, enjoys them because of unions.

Now I don't get any of those benefits, but I can clearly see the need for them, and the continued assault on the service they provide is only for the benefit of a small group of people.
