Teamsters union members in Louisville, Ky., overwhelmingly rejected a part of a contract with United Parcel Service Inc., creating more headaches for the company as it looks to end months of negotiations with its labor force.

In a vote counted on Thursday, the Teamsters' local bargaining unit rejected the supplement 2,804 to 185. Supplements determine issues such as health-care benefits, the number of added new jobs, wages for part-timers and overtime restrictions.

It was the second time the employees in Louisville rejected the supplement. It covers around 8,000 UPS employees who work at the delivery company's massive Worldport air operation, which flies millions of packages in and out for sorting.

"Our members won't accept a bad supplement," said Fred Zuckerman, president of Louisville's Teamsters Local 89. Reasons for rejecting the supplement included UPS's delays in adding more equipment for workers to get from the parking lot to their areas of work at the Worldport air hub more quickly, including more shuttles and metal detectors. In addition, he said the company removed a pension-contribution increase for some workers and a $1,000 bonus that were in the last version of the supplement.

"We're going to continue to work to attain a settlement," a UPS spokesman said. A spokeswoman for the national arm of the International Brotherhood of Teamsters declined to comment.

The rejection of the supplement is a setback to UPS's attempts to implement the five-year master contract that was approved in June by the company's domestic package-delivery employees. Despite winning approval last summer, the contract can't go into effect until local unions have resolved all outstanding supplements and riders.

Seventeen were initially rejected, but most of those have passed, including those for the large central, southwestern and western regions. Only three remain to be passed, including Louisville.
