US Steel announced this week that 677 workers could be laid off at its Lone Star Tubular Operations in Texas, citing weak demand from the energy industry.
The company has not set a date for layoffs to begin, but they will reportedly be temporary.
The plant was idled last year before returning to normal operating levels, but a spokesperson told local media that the long-term downtrend in oil prices and resulting drop in energy pipe demand has necessitated layoffs again.
