The Teamsters union representing 340,000 UPS workers called off strikes in seven states, after the company agreed to settle a handful of outstanding grievances from employees.

According to an August 12 release from the Teamsters, the union was prepared to conduct a strike at UPS's largest air hub in Louisville, Kentucky, as well in Illinois, California, Massachusetts, Pennsylvania, Georgia and Ohio. Workers claim that in Louisville, UPS redirected airport distribution services away from certain employees to workers paid a lower rate. Elsewhere, the Teamsters allege that UPS also sent out illegal buyout offers and forced employees to work past hourly limits.

With picket lines ready to assemble in the early morning hours August 12 across seven states, the Teamsters secured a handful of settlements from UPS on outstanding grievances as well as a first contract for newly organized workers, the union said, indicating the fight was far from over.

“The Teamsters have lost all patience with UPS’s ongoing attacks on our members’ rights and our contracts. "The gloves are off," said Teamsters general president Sean O'Brien. "Our union’s actions Monday and Tuesday are just the beginning of an aggressive new chapter for the Teamsters at UPS. We will be UPS’s conscience.”

Although UPS reportedly agreed to settle several outstanding grievances, the Teamsters claim that the company is still violating the union's master labor agreement, by failing to make good on a promise to provide thousands of additional vehicles with air conditioning to drivers, and by dragging its feet on its obligation to create at least 22,500 new full-time positions.
