UPS drivers are getting closer to a strike as talks break down at 4 a.m. amid finger-pointing squabbles.

 Negotiations reportedly ran until 4:00 a.m.—and both sides are already pointing fingers at the other for the breakdown in talks.

“UPS walked away from the bargaining table after presenting an unacceptable offer to the Teamsters that did not address members’ needs,” the union wrote in a release. “The UPS Teamsters National Negotiating Committee unanimously rejected the package.”

Negotiations reportedly lasted until 4:00 a.m., and both parties are already blaming each other for the failure.

"UPS walked away from the bargaining table after presenting an unacceptable offer to the Teamsters that did not address members' needs," the union said in a statement. "The UPS Teamsters' National Negotiating Committee unanimously rejected the package."

However, the corporation stated that this was not the case.

"The Teamsters have stopped negotiating despite historic proposals that build on our industry-leading pay," UPS said in response. "We have almost a month to negotiate." We have not gone away, and the union owes it to stay at the table."

UPS and the union have already agreed on a tentative pay rise, truck air conditioning, and the elimination of the two-tier driver system, which paid weekday drivers more than weekend drivers.
