Under the tentative agreement, existing full- and part-time UPS union workers will get $2.75 more per hour in 2023, and $7.50 more per hour over the length of the five-year contract. The agreement also includes a provision to increase starting pay for part-time workers, which the union had called the most at risk in the company’s workforce of being exploited. Starting pay for part-time workers will be $21 per hour, it said, up from $16.20 today.
