Arkansas does not set a fixed number of hours, but employers must schedule work on election day so that each employee has time to vote. The time is unpaid.
Voting leave in Arkansas
Good to know
Most voting-leave laws only apply when your work schedule does not already leave you enough time to vote, often two or three consecutive non-working hours while the polls are open. Where leave is required, the employer can usually decide whether you take it at the start or end of your shift. Early voting and mail-in ballots can change what applies to you. This is general information, not legal advice.
