ASLEF now needs to make sure it does as effective a job as the RMT in telling the public the dispute is primarily over changes to terms and conditions. I think the RMT did a good job, but the media still seems to think drivers are just after money and are greedy because they're already well paid.
Even the Guardian, which has generally supported the strikes, has recently appeared to have less sympathy and has trotted out the same lines about how much money drivers want, how much they're paid (and saying that some earn six figures, but not implicitly saying how that's achieved, such as doing lots of overtime) and so on.
If the Government wants to settle things, it knows what it has to do. With an election looming, it surely cannot want these battles to continue.
