US delivery workers swelter in record heat – many without AC in their vans

Amid rising temperatures last year, unionized UPS workers made heat an issue - but despite a key contract win, workers say little progress has been made

Seth Pacic works as a United Parcel Service delivery driver in Dallas, Texas. In the summer, he has a second full-time job": staying cool.

Each morning, Pacic packs his cooler full of ice, water jugs and hydrating foods such as pickles and grapes. He straps frozen cooling packs to his wrists, hangs another around his neck and ensures he has powdered sports drinks and a battery-operated fan on hand.
