MINNEAPOLIS (AP) - Delivery drivers from Teamsters Local 120 voted unanimously to strike O'Reilly Auto Parts in Minnesota unless the company agrees to a renewed labor contract that increases pay and safety standards.

Union officials announced the move Friday in a statement.

O'Reilly spokesman Mark Mertz says the union has misrepresented the position that the company has taken through the course of negotiations regarding pay and safety issues.

The workers deliver auto parts to most of O'Reilly Auto's 99 retail stores across Minnesota from a distribution center in Brooklyn Park. They have worked without a contract since Dec. 10, and have been in negotiations with the company since September.

A union representative says talks resumed on Friday but declined to comment beyond the union's statement.
