SAN DIEGO -- Tuesday marks the second day that stores have gone without deliveries from Teamster drivers, 10News reported.

On Monday, the Teamster's union turned up the heat by refusing to make deliveries to the three grocery chains involved in the supermarket strike and lockout.

Teamster trucks are not at Albertson's, Ralphs or Vons, but small independent truckers and those owned by the chains are still making deliveries.

In front of stores, striking clerks vocally urge shoppers to go somewhere else.

The strikers are getting paid for walking the line, but earn less than half of what they make on the actually job.

One clerk, Dawn Arriola, almost cried when 10News asked what the strike meant for her family's holiday.

Arriola said, "Luckily we have family to help us and I have my husband. But, you see people coming out with big baskets of groceries and all the extras and the ones that are coming I don't think have a heart."

The strikers are counting on the picket lines and shortages caused by the Teamsters to pressure the stores into settling.

Nick Minutelli, another striking grocery clerk, said that 80 to 90 percent of the stores goods are delivered by Teamster truckers.

Minutelli said the stores can hire nonunion truckers but that will take several days.

The Associated Press reported that the stores said they have contingency plans to keep the stores stocked and open on a regular schedule. The stores said the unions are more interested in disrupting business than settling the strike.
