Bill Shranko says Yellow-Checker-Star Transportation was only able to fill two-thirds of its 600 cabs the first shift after the strike took effect early Sunday.

Nevada Taxicab Authority spokeswoman Teri Williams didn't immediately respond to messages seeking comment on the strike's overall effect on Las Vegas.

The chief negotiator for the union representing drivers says the main sticking points are over pay and working conditions.

Paul Bohelski (boe-hal-skee) says about 1,400 of the company's 1,700 drivers are union members and over 1,000 of them are participating in the strike.

Last month, the company unilaterally implemented a contract rejected by 70 percent of members of Industrial Technical Professional Employees Union Local 4873.
