UPS tentatively agreed to equip its delivery trucks with air conditioning for the first time following union negotiations between the company and the Teamsters. “Air conditioning is coming to UPS, and Teamster members in these vehicles will get the relief and protection they’ve been fighting for,” said Teamsters General President Sean M. O’Brien. However, the agreement only requires AC in new delivery vehicles purchased after January 1st, 2024, meaning it won’t likely spell relief for drivers this summer.
