Under California law, if employees don't have sufficient time to vote in a statewide election outside of working hours, they're entitled to enough paid time off from work so that, when added to the voting time available outside of working hours, they are able to vote.
Unless the employer and employee mutually agree otherwise, time off must be scheduled at the beginning or end of the regular work shift, whichever allows the most free time for voting and the least time off from work.
No more than 2 hours can be taken without a loss of pay. If the employee knows or has reason to believe that time off will be necessary to be able to vote on election day, the employee must give the employer at least 2 working days' notice that time off for voting is desired (CA Elec. Code Sec. 14000).
An employer must post the provisions of the time-off law not less than 10 days before any statewide election. The notice must be posted conspicuously at the workplace, if practicable, or elsewhere where it can be seen as employees come to or leave from their place of work (CA Elec. Code Sec. 14001).
