The UPS Teamsters flexed their collective muscle to win most of their demands from the world’s largest delivery company. There are numerous lessons to be learned from what has transpired between the Teamsters and UPS during this year’s #HotLaborSummer. According to the U.S. Department of Labor, “non-union workers earn just 85 percent of what unionized workers earn.” Additionally, “when more workers have unions, wages rise for union and non-union workers.” There is an upward pressure on wages for all when groups of unionized workers win wage benefits for themselves. Instead of giving in, UPS Teamsters walked away and began their practice strikes, likely betting that the company would cave. The UPS Teamsters had initially demanded a starting salary of $25 an hour for its part-time workers, who are nearly half of all the company’s workers.
