I doubt it, at least for most areas. Does anyone know if bulk carriers are part of this, or if it really just affects container ships? Even if bulk carriers are affected, most oil/gas moves through pipelines between different areas of the country (and that might include importation from Canada?), and I doubt much comes in through the ports under the strike. But I’m open to correction on that point.
Longshoreman are not involved in tanker operations.
Just container ships. Not things like ore or grain shipments. I would imagine that fuel shipments go to different ports.
