UPS Supply Chain Solutions Inc. illegally insisted that a Teamsters union local in Puerto Rico translate its proposal for a collective bargaining agreement from Spanish to English, the National Labor Relations Board ruled.

A two-week strike by 150 Chicago Teamsters targeting Dr Pepper Snapple Group Inc. continues after drivers voted overwhelmingly to reject the soft drink company’s latest contract proposal, union officials said June 8.

UPS Inc. workers authorized their union to call what would be the first strike since 1997, giving negotiators more leverage in talks to replace a labor contract that expires at the end of July.

More than 150 Teamsters walked off the job in suburban Chicago early May 22 after a wage dispute with a Dr Pepper Snapple Group Inc. subsidiary.

The 600 members of Teamsters Local 830 agreed May 12 to a new five-year contract with Liberty Coca-Cola Beverages, ending the threat of a strike, the company said.

An independent investigator has notched up his probe into whether top Teamsters leaders accepted undisclosed gifts from a business that brokered health benefits for the union.

Leaders of Teamsters Local 830, whose members load, drive and deliver drinks from breweries and soda plants in the Philadelphia area, said members are ready to strike to preserve their pensions as tough negotiations with Coca-Cola’s new regional affiliate face an impasse over continued funding for the workers’ pension plan.

The largest union for U.S. truck drivers, which has taken a cautious view of autonomous vehicles, called for stronger safeguards after a self-driving SUV operated by Uber Technologies Inc. killed a pedestrian in Phoenix on March 18.

Contract negotiations between UPS Inc. and the Teamsters Union began in January with the union and the package delivery firm taking a measured approach to reaching a deal before the July 31 deadline.

Cuts made last year in the pension payments to retired Teamsters could be restored under federal legislation being touted by U.S. Sen. Charles Schumer.
