Nearly 40,000 workers will see a pay increase on July 24 when Idaho’s minimum wage increases to $7.25 an hour. Forty percent of the affected jobs are in food service and retail sales. For jobs where people earn tips — bartenders, waiters and waitresses, for example — the minimum wage remains unchanged at $3.35 an hour, but employers must ensure tips provide another $3.90 an hour and combined with wages, equals the new minimum. If the combination falls short, the employer is required to make up the difference.
