Well you may be right.
But if the union disagrees on that point, they have the right to strike and the fact it inconveniences you and me doesn't negate that right IMO.
I'd argue it is having an effect on the employer because at least in helping them trash their reputation. But I agree it's an usual situation because the company doesn't lose any revenue because the government (i.e. us the taxpayer) is picking up the financial cost.
But what you're arguing is that people should never go on strike, or decline to work extra hours, if it inconveniences others.
That is the very definition of industrial action - if no one feels its effects it's kind of pointless isn't it?
That said, I do agree with what Bozza said elsewhere...
I understand that. But where we disagree is thinking we're owed an apology for industrial action. It's the company's job to provide a service. Relying on people working overtime is not an adequate way to do that.
Tomorrow's disruption is mainly because ASLEF drivers are declining to work overtime. Which is entirely their right. Unless you think people should be forced to work overtime?
