VTA’s final contract offer to workers last week included a wage increase of 9% over three years, keeping the employees as the second-highest paid in the Bay Area and the fifth-highest paid in the country. The union is seeking a 6% raise per year over three years and wants to add a clause guaranteeing arbitration for contract disputes.

Mediation failed to end the VTA and ATU Local 265 strike, leaving 100,000 riders affected as the union fights for better contract terms, despite a VTA lawsuit over the no-strike clause.

The latest attempts at mediation between the Santa Clara Valley Transportation Authority and the union representing striking VTA workers did not reach an agreement, transit officials said in a release Friday.
