The United Parcel Service is preparing for the second-largest employee strike in the company’s history, which could begin as early as Monday.
The company said it was clearing out all of its freight shipments this week to ensure it was completely empty by Friday, ahead of a potentially massive driver strike.
According to Fortune, 11,600 UPS Freight workers, members of the International Brotherhood of Teamsters, could go on strike Monday if a new five-year labor agreement cannot be ratified on Sunday.
“The company has now begun discussions with UPS Freight customers to inform them of the potential for service disruption and the need to arrange alternative carriers. Because we do not have a guarantee against a work stoppage, we cannot afford to put our customers’ volume at risk of being stranded in our system,” UPS said in a statement.
In a statement, the Teamsters union wrote, “This could all have been resolved by the company [UPS] addressing the key issues at the negotiating table.”
UPS Freight is a division within the company’s small-package division, which employs 243,000 sorters and truck drivers.
