Using your logic the miners were just striking to bunk off work. It would have had much more impact if they did it on their own time. Which is your bullshit opinion.
The kids strike would have had no impact on a weekend. No one would care.
So let me get this right - you're supporting the kids bunking off school to protest about climate change but you're comparing this to miners who were striking in support of a fossil fuel ? Really Plooks, you're stupid.
