It can be clearly argued that both strikes are well founded and against genuine grievances, and separately would go ahead. I think arguing that one is a sympathy strike for the other would not get very far. However, what would the legality be of deliberately organising the strikes as to cause maximum disruption? That is, to take two separate actions and combine into one protest?

I'm guessing that there is some kind of rulebook for strikes out there, whether written or no. But using a pair of two-day strikes (or whatever) at different ends of a week would allow them to disrupt services for the entire week.
