TORONTO - Ontario's striking driver examiners have rejected the latest offer from their employer, Serco DES Inc.

United Steelworkers Local 9511 says the vote against the offer by DriveTest workers was 78 per cent.

The union, which had urged workers to reject the offer, is calling on the company to return to the bargaining table.

The strike, which began in August, affects 93 full-time and part-time DriveTest sites, which grant or renew licences to novice drivers and those over 80.

The work stoppage, however, doesn't affect those who simply need to renew their licence without taking a test as they can still renew at Ontario Driver and Vehicle Licence Issuing Offices.

Job security is a major issue in the dispute.
