Short of losing your job, having your work subbed out must be one of the worst things that can ever happen. So that gives rise to the next question, what do your CC think about it? Given enough support I'm sure the management could be persuaded that a series a four hour strikes might be more expensive. And this time play them on social media the whole way along. The slime in management don't like nasty social media postings because they can't control them. The rumours, noise and threats can start now if someone provides a link.
Best of luck guys.
