UPS and Teamsters at loggerheads as strike deadline looms

UPS has begun training non-union workers as contract negotiations with the Teamsters union have stalled.
The current contract covering 340,000 UPS workers represented by the union expires on July 31.
The union has authorized a strike if no agreement is reached, which could disrupt UPS operations and cost billions.
Key sticking points in negotiations include higher pay for part-time workers.
Both sides say they hope to avoid a strike, which would be the first in 25 years, but are preparing for that possibility.
