OAKLAND, Calif. - Transit officials warned San Francisco Bay area commuters that train workers will likely strike a second day, and urged riders to find alternative transportation options.

The Bay Area Rapid Transit agency said Monday evening that there had been no progress in labor negotiations with its two largest unions.

BART service was suspended Monday after the current labor contract expired Sunday without agreement on new terms.

Antonette Bryan of the Amalgamated Transit Union Local 1555 said BART had not reached out to them since Sunday, so expected a second day of walkout.

Workers want a 5 percent raise annually over the next three years. BART has offered a 1 percent annual raise over four years.

BART also wants to raise the health care premiums and have workers pay into pensions.
