No, this is not a trivial problem, it is more like a prisoner's dilemma. A great majority of union members can agree that there should be a strike in favor of greater protections, remuneration, or benefits, but it is still in each of their individual interests to continue to work for their own benefits. Put differently, they each want the collective to strike, while continuing their own work. I suspect that a 'strike' would involve most/all of the members delaying submission of findings, but continuing any work that was 'low visibility' (i.e. didn't require outside resources).
