The American Red Cross in Philadelphia says striking employees have blocked a blood delivery to a hospital.

Red Cross spokesman Anthony Tornetta says members of Teamsters Local 929 had to be told Thursday that a 2-year-old child's life depended on a blood delivery before they would get out of the way. He says the Red Cross is seeking a court order limiting the union's disruptions.

Union Vice President Rocky Bryan couldn't immediately be reached on his cell phone.

The union represents about 110 employees who pack, ship and deliver blood to Philadelphia-area hospitals and help at blood drives.

The strike, which began Thursday, does not affect Red Cross disaster services. That work is handled by another Red Cross branch.
