NOT A PROBLEM, unions are only 6% of the private workforce. So this means NOTHING to the country (well, according to one person here).
This strike affects the supply chain - how? We were already getting very limited delivery of goods to retail centers, and this merely relieves the pressure on the remainder of the supply chain, so the land transport can be diverted to making other deliveries, of products that are also in short supply.
What if there is a strike called, and nobody notices?
