I agree with the majority that the risk of losing the batched concrete alone would not be sufficient to divest the striking drivers of statutory protection. As Glacier acknowledges, wet concrete is a perishable good. Ibid. And the Board has repeatedly reaffirmed that the loss of such perishable goods due to a mere work stoppage does not render a strike unprotected.
